FAQ

Frequently Asked Questions


Pool surface is prepped, for a renovation/replaster project, the replaster is a completely different process from plastering a brand new pool. Many homeowners tend to think that a replaster process is the same as new pool plaster project, but it is not. The reason is you are dealing with a completely different bond between the finish and the sub-straight (foundation). You are working with an existing product as opposed to a new product. 
The installation of a new plaster surface causes fluctuations in the water chemistry. The alkalinity, pH and calcium levels will rise while the surface is curing. The new plaster is susceptible to staining and discoloration during the first four weeks. The proper curing procedures will help reduce these imperfections plus scaling, pitting and gray streaks or spots. These procedures will also reduce the amount of “plaster dust” on the pool surface and will result in a smoother finish for the pool users to enjoy.

Schedule / Payment

R.O.W. CUSTOM POOLS will provide you with a project contract. All completed projects are to be paid upon the day of completion, unless set up as scheduled deposits or payments on the contract. Any delay in payments as stated on your contract will impose a running 5% per day charge of the outstanding balance until paid.

Do you offer a payment schedule?

Yes, payments are typically divided according to the work being completed.

How will I pay for renovating or adding to my existing pool?

There will be a down payment of 10% of the total cost due at contract signing, then there will be a progression of payments at the end of each phase

How much can I expect to pay for a pool?

We don't give estimates through our web site , we suggest to call our office to schedule an appointment with one of trained estimators for free quote. Request an Appointment click here

What options are available to finance my pool?

We accept check and credit card {Visa , Master, Discover & American Express cards accepted only}. Credit cards will be charged an additional processing fee. We do not finance pools, nor can we recommend anyone who does.

Add Ons

What else should I consider doing to the pool at the same time as it is being resurfaced?

This is the time to consider many items. The list below is to provide you with a checklist of items that are sometimes overlooked when a pool renovation is contemplated. Contact our office to discuss further with you any pool upgrades you may be considering.


Here are a few to consider:
• Upgrade Finish
• Tile and Coping: The time to replace tile and coping is before a new pool finish has been applied.
• Cantilever Decks: You can give your pool a new look by cutting back the cantilever deck and installing rock or brick coping around the edge of the pool.
• New Decks: Consider replacing your decks in conjunction with your pool renovation. If decks and the pool are being remodeled together, this gives us the opportunity to set your new pool coping and tile absolutely level since we are not inheriting existing decks that may or may not be level.
• Skimmer: Whether or not decks are being replaced, your skimmer should be evaluated for possible replacement. Certain skimmer designs are problematic.
• Pool Light: A pool light that looks fine in the old pool sometimes no longer looks that good against the new pool finish. We offer upgrade lights with color variation capability. We can also assist in verifying that your light circuitry meets current electric codes. For example, many older installations do not have GFI shock protection.
• Fittings: Unless otherwise directed we will replace only “standard” type fittings. “Screw-in” type fittings are replaced only when specified on the contract.
• Wallsteps: Plastic wallsteps are often in poor condition and should be replaced prior to the pool being refinished.
• Pool/spa Suction: Inlet suction in your pool/spa can be especially hazardous to children. It is important to review how water is returned to the equipment pad and consider “split-suction” in some cases.
• Trim Tile: Trim tile is eliminated when a pool is refinished. If you wish to replace trim tile on your steps and benches, it must be specified on the contract.

Weather Permitting

Q: What happens if it rains?

A: Rain causes delays on the job. We cannot pour concrete, install tile or coping, or plaster a pool during the rain. In most cases, we will not work during rain days.

Q: When will I be schedule if there are weather delays?

A: Our superintendent will make decisions based on the latest weather information we have at the time not to work our crews in the mornings. This will result in losing the entire day. In most cases, your project could be delayed by as many as 3 days for every day of rain. Typically, pool contractors have several jobs that are simultaneously under construction. There is also the dreaded domino effect. This domino effect even can occur when you would least expect it—it’s the phenomenon known as a “sunshine delay”: Even if a single drop does not fall at your house, a downpour in another part of town may delay crews from finishing work on another pool. This in turn holds up their arrival to work on your pool! In addition to rain, other weather conditions can sideline progress (i.e. pool plaster cannot be applied during rain & gusty winds that could blow sand, leaves, or other debris into the smooth, freshly applied material).

Re-plaster Process

What is plaster?

Plaster is the finished surface material of the pool that is applied over the gunite.

How long will it take to restore our pool?

Depending on what is being done to your pool, we try our best to have the job done in 5-10 days depending on weather and time of year

How will you replaster our pool?

Depending on the condition of the plaster, we will either chip the existing plaster or, if the finish is solid, we will sandblast and multicoat the existing plaster and apply the new plaster over the bond coat.

How long will it take to re-plaster my pool?

For your convenience, we schedule all are replastering projects to occur on consecutive days. The number of days will depend on the amount of work ordered and on weather conditions. However, here is a typical project schedule:

PHASE 1 – We drain your pool.
PHASE 2 – A crew will remove your old plaster, tile, coping, etc.
PHASE 3 – New coping is installed.
PHASE 4 – Your new tile is installed.
PHASE 5 – We plaster your pool and begin refilling it with water.

When plaster is installed, your pool is "substantially complete." Plaster is a smooth waterproof material, which coats the interior surface of your new pool. The Plaster Crew will install the interior fittings such as the main drain and rope anchors.

When they are through, the Plaster Crew will wrap the end of your garden hose with a rag, and leave the hose turned on, resting in the deep end of your pool. Once you have started filling your pool, please follow these important guidelines:

1. DO NOT, UNDER ANY CIRCUMSTANCES, STOP THE WATER UNTIL IT REACHES HALFWAY UP ON THE TILE! This is critical! If the water is stopped, there is a high risk that the fresh plaster will develop a permanent stain or ring at the water line. Or the remaining exposed area could dry out and develop checks or cracks.
2. Try to protect your new pool from dust, dirt, and leaves while it is filling. BUT DO NOT GO INTO THE POOL TO REMOVE DEBRIS! You may use a FINE MIST SPRAY to hose down dust or dirt into the pool water.
3. Please do not turn on any switches or try to operate the pool pump or light. We will turn on the equipment after the pool is full. Any attempt to operate any of the equipment before the pool is full and before we have properly prepared it could lead to electrical shorts or serious equipment damage.
4. CALL our office when the water reaches halfway up the tile. We will schedule a site visit and perform the Start-up

How long will it take to fill our pool?

The length of time required to fill a pool depends on a number of variables such as your local water pressure, the number of hoses being used, and the size of the pool. The average pool takes 24 - 36 hours to fill and it is important to remember that the water should not be turned off until the pool is completely full.

Our pool was just prepared for resurfacing. Why is the surface very uneven with large holes and streaks?

It is important that our crew remove all of the old delaminating plaster prior to resurfacing. A rough surface is expected in most pools since not all areas are delaminating. Once the new plaster or pebble has been installed you are not able to see the previously cratered areas.

We just had the pool re-plaster and when the lights are on at night the surface looks rough and lumpy. It feels smooth to walk on and looks fine in the daytime. If I hadn't noticed the lumps and gouges, I would have believed the pool was perfect.

Throwing a little light across a surface will illuminate every imperfection (try a flashlight across a counter top) that you could never see otherwise. It's true of any pool surface, but less noticeable in say, a commercial pool, where multiple lights soften shadows. As long as it isn't rough to touch or walk on, this won't affect the service life of the surface.

You have two options:
Soften the light by using a smaller wattage bulb or a color cover over the lens (available in blue, yellow, green and red) OR aim the return 'eyeballs' up and have the system run at night during the hours you're likely to be out by the pool. When you ripple the water, imperfections in the pool surface disappear.

Start Up

Pool care starts the minute your pool is full of water. The start up of your pool is crucial, and if you’ve never started up a pool before, we recommend you look at our Start Up Recommendations. We advice our customers to hire a professional pool service technician. Find someone that you can trust to care for your pool as if it were their own.
Pool start-up
Once your pool is full of water, it will require extra attention. A pool start-up includes brushing, filtration, and chemical balancing. If you are not comfortable with these procedures, we suggest that you consult with a pool service professional.

The following are additional guidelines to be followed during the start-up period:
As plaster cures, especially during the first 30 days, it is important to remove plaster dust in a timely manner by brushing and to stabilize water chemistry in the pool. Since chemicals can have a significant impact upon the life of your plaster it is suggested that only persons trained in this area introduce chemicals to the pool. 

A replastered pool must be brushed at least twice per day until there is no longer visible plaster dust churned up by the brushing. Inadequate brushing may result in the plaster dust becoming permanently affixed to the surface of the pool.

Start the pool equipment once the pool has been filled. Run the filter 18 hours per day for at least a week subsequent to plaster. Make sure that there is main drain suction to filter the dust from suspension in the water. Monitor filter pressure as the filter may need cleaning during this period due to the accumulation of plaster dust. Do not turn on the heater for at least ten days and longer if the pool is not in chemical balance.

Ph Maintenance, filtration, brushing and water balancing are all essential to maintaining a smooth clean finish that will last for years. Plaster is, however, made from reframed materials applied under conditions beyond our control and is seldom blemish free. No two pools ever look the same. Air temperature, wind, moisture, and exposure to direct sunlight affect all phases of construction and therefore, the finished ‘look’ of your pool. You may notice anyone of the following conditions. These are not considered a deficiency in materials or workmanship:
  1. Surface checking and crazing-Cement shrinks as it cures. These do not leak, and are usually to ‘tight’ to require patching. More noticeable in colored plaster
  2. Discoloration:
    1. Brownish-Usually organic from dust/dirt 
    2. Greyish-Usually calcium deposits. ALL POOLS have some calcium deposits. Keep to a minimum by adhering to 2, 3, and 4 above. 
  3. Dark spots or blotches on colored plaster-This is the original color of the plaster-Plaster without any calcium deposits on it.
  4. Dark specks in colored plaster-Inherent in cement pigments. 
  5. Mottling-Blotchy, cloudy, or discolored wavy look-caused by the curing process of cement.
  6. Plaster feels rough throughout the pool-Due to chemical imbalance or improper brushing.

After Care

When can I swim in my pool after it has been plastered or pebble-coated?

Once the pool is filled, the equipment is started and the water is balanced. This takes a few hours, then you’ll be ready to begin enjoying your pool!

How will I handle ongoing maintenance of my pool and spa?

We can refer you to a weekly pool maintenance company

What special care needs to be taken during pool start-up after replastering?

Once your pool is full of water, it will require extra attention. A pool start-up includes brushing, filtration, and chemical balancing. If you are not comfortable with these procedures, we suggest that you consult with a pool service professional.

Why do I need to brush pool?

Clearing The Scale (Dust)You may notice plaster scale (dust) on the bottom of the pool. This is normal and will go away with proper treatment and brushing. The main objective in starting-up a pool is to clear or get rid of scale (dust) and to balance water chemistry in the pool as quickly as possible. Do not use a wheeled vacuum for three weeks after plastering. The use of a brush vac is recommended during the first three weeks to avoid marring the plaster.

On some pools you may have to turn off the main drain so that you can vacuum. When you have vacuumed the scale (dust) from the pool it is important to clean this residual from the filter right away. Remember to recharge the filter if it is a D.E. filter.

It is okay to vacuum the scale (dust)?

The more you brush the pool the better it will look. The entire pool should be brushed preferably twice a day until the water is balanced and the plaster scale (dust) has gone away. The pool should be brushed after each vacuuming.

The filter pump should be on with the main drain open. Add chlorine in small amounts as needed to the pool until after the scale (dust) has been eliminated, the water is balanced and stabilized and conditioner added.

How do I remove "RING" around the pool?

If you have a pool or spa without waterline tile and need advice on removing the "ring" around the waterline of the Pebble Tec, the following instructions are basic guidelines. This ring is commonly referred to as a "calcium ring" or "mineral buildup." Usually any type of cleaner designed to clean calcium off of waterline tile . When using these cleaners/chemicals follow the directions on the container. It is a good idea to spot test a small area first. Lower the water level to expose the waterline and apply the cleaner to an area of about 8-10". Next, scrub the area with a nylon brush and start rinsing with a hose while scrubbing. The cleaners can be rinsed into the pool, but remember to use caution while working with these chemicals as they may contain acids. Repeat as necessary. Always follow the instructions on the container.

What on-going maintenance needs to be performed?

Once your newly remodeled pool has been chemically balanced and all plaster dust has been filtered out, you will want to establish a routine maintenance schedule to thoroughly enjoy your pool and protect your investment.

R.O.W. CUSTOM ENTERPRISES does not provide pool maintenance services. You can either maintain the pool yourself or contract with a pool service professional. It is important that the pool chemicals be closely monitored to maintain the proper chlorine, acid, and pH levels. Your heater, solar water heating system, cleaner, and filtering system should also be checked and maintained throughout the year.

The best "cure", is prevention. Keep track of your chemical balances, and maintain the pH. Don't forget to stay on top of the situation even in the winter. When the water is cold and you don't want to check the pool, is when most problems happen. So keep the water maintained and balanced all year round.

Cracks

Cracks in your pool surface are concerning but common. The most common cause of pool cracking is ground movement. Not all cracks need to be addressed as emergencies.

What is crack repair?

The focus of crack repair is to prevent further leakage of water through existing pool cracks. In some cases, the structural integrity of the pool will also be addressed.

Will the fix be permanent?

Since all crack situations are different, there is no guarantee that the fix will be permanent. Unless the cause of the crack is identified and addressed, the pool may continue to crack.

Do all cracks need to be repaired?

Surface cracks are not uncommon in swimming pools. If there is water loss in the pool, these cracks can be dye tested to see if they are leaking. Surface cracks that do not leak do not necessarily need to be repaired.

What is done?

The first step is to sawcut any cracks and chip out the plaster to expose the gunite. At this point the crack is evaluated for repair. Any cracks smaller than 20 mil will not accept injection of epoxy and will be topcoated only. The topcoat provides a flexible waterproof membrane to prevent water leakage through the crack. In cases where the pool has cracked in excess of 20 mils but not greater than ¼”, the crack will be pressure injected with epoxy, or in essence “glued” back together. The epoxy will be allowed to set for several days, and then the epoxied crack will also be topcoated with a flexible waterproof membrane. In each case, after the topcoat is complete the materials will be allowed to cure, at which point a plaster patch can be applied. In severe cases where there is damage to the gunite or to the rebar in the gunite, areas may need to be jackhammered out and rebar replaced/added to solve the problem. In cases where this work is required, additional charges will apply.

Does have my pool have a leak?

MY POOL IS LOSING WATER?
Your swimming pool will experience normal water loss through the process of evaporation here in Nevada. In fact, due to the low humidity and high temperatures during our summer months, you can lose a 1/4″ or more a day. If you have a water feature you are running regularly in the summer, the water loss will be even higher. Closely inspect the swimming pool interior shell for cracks and defects. If you identify a structural problem with your swimming pool, we recommend that you request an appointment with one of our skilled service technicians.. Check the flexible backwash hose for any water leakage. If water is leaking out of this hose, the "O" rings will need to be replaced inside the backwash valve.

I have a leak in my swimming pool. Is it coming from my swimming pool and spa plumbing?

Many pool leaks have been traced back to the swimming pool plumbing, particularly, originating at the skimmer or a leaky pump. Just pop the lid off the skimmer. If you notice a crack in the skimmer housing, there is a good chance you might be losing water there. However, we are not leak detection specialists, so it is recommended that you contact a professional leak detection company. This way you can isolate the location of the leak, and then we can help you out!

How to spot for Pool or Spa Leaks:
Do you suspect your pool or spa is leaking? Here are several reliable ways to check.
• The Greasy Guide ‑ Use a grease pencil to mark the water level of the pool at the skimmer. Check the mark 24 hours later. Your pool should lose no more than 1/4 inch per day. Otherwise, a leak is indicated.
• The Bucket Test ‑ Place a bucket filled with pool water on a pool step (weight it with a rock or brick). Mark the water level on both the inside and the outside of the bucket. The starting point levels should be about the same. Check the mark 24 hours later. If there's a greater drop in the line on the outside of the bucket, a leak in the pool is indicated.

Do you suspect your pool or spa is leaking? Here are several reliable ways to check.
• Algae or other persistent water quality problems indicating imbalances in the chemistry can occur when a leak prevents the water level from staying constant;
• Loose tiles or cracks in the pool deck;
• Cracks and gaps in the bond beam; or
• Water‑saturated soils in the area around the pool, pool pumps or plumbing.

When in doubt Contact LEAK COMPANY to further assist you in determining if you pool has a leak.

Determining the Location of the Leak:
If you determine that your pool is losing water, turn off the filtration system and note where the water stops dropping.

• If the water stops at the skimmer, the leak is probably in the filtration system. The lines may crack at vulnerable elbows and fittings that are under stress from shifting soils.
• If the water stops at the light, the leak is probably there.
• If the water drops below the light, then there may be a leak in the drain at the bottom the pool.

If you suspect you have a leak in the filtration system these clues may help you pinpoint the location:
• If you see bubbles in the return water when the pool's pump is running, it's likely there's a leak in the suction side of the filtration system.
• If the pool is losing more water while running the pump, then water is being lost on the return side of the system.

You can save money by testing your own pool for a water loss.
The Bucket Test:
Please note: We are not leak detectors but we provide this information to help pool owners. When a leak detection company finds the leak we can repair leaks.

A simple test will confirm a leak in a pool or spa: **DO NOT LET CHILDREN PLAY WITH ANY BUCKET**

1. Bring the pool water to its normal level.
2. Fill an empty bucket with pool water to about one inch from the top of bucket (by filling the bucket close to the top you are ensuring that air movement over the surface of the bucket will similar to that of the pool).
3. Place the bucket on the first or second step of the pool. To keep it from floating away it may be necessary to place a few bricks or rocks into the bucket (by placing the bucket in the pool water you are ensuring that the water temperature of each will be similar).
4. Mark the water level inside the bucket.
5. Mark the water level of the pool on the outside of the bucket, on the pool wall, or skimmer face plate.
6. Operate the pool for 24 hours as it had been operated when a leak was first suspected.
7. After 24 hours, compare the two levels. If the pool water (outside mark) goes down more than the inside water level, there is probably a leak.

Equipment

MY POOL LIGHT IS NOT WORKING?

• Check your circuit breaker and reset if necessary.
• Check your G.F.C.I. (Ground Fault Circuit Interrupter) and reset if necessary.
• If your pool light is tied into a remote system, test your batteries. Are the remote frequencies set properly?

How do you change the light in my pool?

Light bulb – remove the screw on the top of the chrome ring around the light. There will be enough cord wrapped around the light unit to allow you to bring the whole light unit up onto the deck. disassemble the light (tabs & screws or wire clamp assembly) and change the light bulb. We recommend changing the light gasket at the same time to ensure a tight seal. Reassemble the light and replace into the niche in the wall and reinstall the screw.

Complete light – Be sure to purchase a light with the correct voltage (120v or 12v). Make sure the light has enough cord to reach your junction box with extra to allow the unit to be put on the deck for future bulb changes. Always make sure the electricity is turned off. Cut the cord directly behind the light fixture. Tie the end of the new cord to the cut end of the old cord and use duct tape to ensure the cord stays together. Working from the junction box, pull the old cord out. This will pull the new cord through the brass conduit leading from the light unit to the junction box. Disconnect the two cords, connect the new cord to the power source and install the new light unit into the niche in the wall

WHAT IS THE NORMAL WATER PRESSURE FOR MY FILTER?

• Each swimming pool system has different water pressure tolerances. Please refer to your original owner's equipment manual and/or startup instructions to identify the range of proper pressure for your swimming pool.
• If you suspect that the pressure is too high, check and clean out all debris from baskets. In addition, check to see if all your equipment valves are set properly and backwash your filter for several minutes.
• If you suspect that the pressure is too high, confirm that the pressure gauge reads zero when the equipment is off. If it does not fall back down to zero, you will need to replace the gauge.
• If you suspect that the pressure is too low, check and clean out all debris from baskets. In addition, check to see if all your equipment valves are set properly.
• If you suspect that the pressure is too low, check to see if the gauge reads zero when the equipment is off. If it does not fall back down to zero, you will need to replace the gauge.

HOW OFTEN SHOULD I LUBRICATE MY BACKWASH VALVE “O” RINGS?

• The standard push/pull backwash valve is a plunger type of valve commonly found in sand and DE filter systems. Inside the valve is a plunger with two o-rings. When the valve is put into the backwash position, the flow of water through the filter is reversed. After putting the valve into the backwash position, the water is pumped out through the backwash rather then being returned to the swimming pool. Typically, a hose is attached to the valve so the operator can direct the water flow away from the swimming pool. Normally, there are four "O" rings in this type of valve. If these rings become damaged, worn or dried out, two things will occur. Unfiltered water may return to the swimming pool and/or the swimming pool will begin to lose water.
• Cap "O" Ring (1) seals the removable cap to the valve body. This "O" ring requires light lubrication and should be cleaned and lubricated each time the cap is removed.
• Shaft "O" Ring (1) is inside the cap and provides a seal where the plunger shaft goes through the cap. This "O" ring requires light lubrication. Apply a small amount of lubricant to the shaft immediately above and below the cap and then work the shaft up and down. This should be done once per month or when the shaft becomes difficult to move.
• Piston "O" Rings (2) are on the pistons or discs of the plunger. These rings require heavier lubrication. TURN OFF YOUR FILTER PUMP. Remove the cap and pull the plunger all the way out. Check the two "O" rings to make sure they are not damaged. They should fit snugly on the pistons with no kinks or twists. Apply a pencil-sized bead of lubricant around each "O" ring and insert back into the plunger. Re-install the cap. This should be done once per month (or as necessary) when the shaft becomes difficult to move.

HOW OFTEN SHOULD I CLEAN THE GRIDS ON MY D.E. (DIATOMACEOUS EARTH FILTER)?

• Most manufacturers recommend that the following procedure be done on an annual basis. Disassemble the filter, clean with garden hose, inspect the grids for tear and holes and re-coat new D.E.
• This type of filter utilizes D.E. powder to strain debris from the water (as recommended by the manufacturer). D.E. is the fossilized remains of plankton (diatoms) that have been ground into a fine powder. The cloth-covered grids within the filter must be pre-coated with D.E. powder for the proper filter operation.
• Pre-coat the filter grids by mixing a combination of D.E. and water. The slurry solution should have the consistency of watered down pancake batter. Slowly pour this slurry into the skimmer while the pump is running. Once the grids are coated, the debris will be removed from the swimming pool water. The water flows through the grids and flows out the end opening into the manifold and returned to the swimming pool.
• Backwashing a D.E. filter is similar to the procedure for the sand filter. By reversing the flow of water, the debris and dirty D.E. are loosened from the grid. This water is washed out of the filter and into the backwash line. After this is completed, the D.E. re-coating of the grids can proceed.
D.E. powder is non-biodegradable and a separation tank may be installed on your backwash line to capture all of the flushed powder particles

Algae

What are my options when my pool turns green?

When your pool turns green you have two options. You can 1. Treat the Water in your pool or 2. Drain the pool, scrub it and start over. The method you want to use depends on how bad your algae problem is and how quickly you need it handled. Treating the existing water in a swimming pool takes a lot of work and scrubbing. The pool must be visited and worked on at least every other day until it is finished and there is often at least one and usually two hours of work to do each visit. The pool needs to be scrubbed, vacuumed, filter cleaned, water balanced and then shocked and treated with algaecide. There are also a lot of chemicals involved.

Can I get rid of the Algae myself?

Yes, It is just a matter of how much work you want to do.

What is the best method for getting rid of Green algae?

The best method is to shock scrub and clean every two days until the algae is gone or just pump it out.

What is the best method of getting rid of Yellow or Mustard algae?

You must scrub the algae constantly as you treat it. At first yellow mustard algae is very hard to scrub but after treatment with proper chemicals it will be much easier to remove.

What is the best method for getting rid of Black algae?

Black algae can be very difficult because if you aren't careful you will spread it everywhere and it is very resitant to chlorine. You need to get special chlorine products to do it properly

Calcium Build-up

Q:Why do I have little rust stains on my plaster?

A: Rust stains can again be caused by improper chemical treatment, but in most cases rust like stains are caused by debris left undisturbed in the swimming pool. If the stains are on the bottom of the pool, it is usually causes by plant life or some other debris left in the pool by a swimmer. If the stains are on the walls of the pool, the stains are more than likely caused by poor water chemistry.

Q:Why are there white, rock like deposits on my tile?

A: They are called calcium deposits or calcium build-up.

Q:What is calcium build-up?

A: There is usually two much calcium in your swimming pool water.

Q:Why do I have calcium build-up?

A: There is too much calcium in your water. Calcium levels should be between (00000) and (0000) parts per million. Again, improper water chemistry is the culprit.

Q:How do I get rid of calcium build-up?

A: A couple ways to remove calcium deposits from your swimming pool tile are by acid washing the pool and using a pumice stone on the calcium deposit or using a bead blaster to remove the deposits. Bead blasters shoot pressurized glass beads at the deposits removing them from your tile. The beads are then vacuumed up by the bead blasting company. If your pool plaster is in good shape, no roughness or stains, you may want to check into bead blasting as an alternative to acid washing.

Chemicals

Why is balancing my pool so important?

If your pool water is not balanced properly, it can lead to skin and eye irritation as well as harm the equipment and surface of the pool

My pool has a white substance floating in the pool. What is it?

Water mold is a whitish, mucous-like substance that looks like shredded tissue paper when floating in the water. It is not harmful to humans, but is unsightly and can clog equipment. It also depletes oxidizer levels, which can other undesirable conditions to occur. Water mold usually begins growing in the lines, and by the time it becomes visible, the growth is often quite heavy.

If I have water mold, what should I do?

If the pool uses chlorine or bromine, the first step is to brush the sides and bottom thoroughly. If you think you might have missed a few maintenance algicide applications, add an initial dose of your algicide (algae and fungal growths usually indicate inconsistent algicide applications). Next, shock with three times the normal dose of Aqua Chlor or Aqua Burn. Allow the filter to circulate overnight. Repeat as necessary. When the procedure is complete, chemically clean the filter.

I keep adding chlorine, but when I test my water, there's no chlorine reading. Why?

The reason for the absence of a chlorine reading is that your chlorine is tied-up. It is combined with amine groups causing your chlorine to be inactive. This is commonly called chlorine demand. What you need to do is shock or superchlorinate your pool. Shocking your pool will cause the chlorine to free up. Double and triple levels of super-chlorination may be depleted within hours of application. Often the pool water will be sparkling and attractive while this problem is taking place. In some cases, the chlorine stabilizer disappears and cannot be measured.

What causes chlorine demand?

There are many causes for chlorine demand and in most cases - there is no one cause for a particular chlorine demand but several combined: algae, fertilizer contamination, excessive chloramine accumulation, rain, pollution, excessive cover debris rinsed or dumped in pool, source water (sometimes municipal water supplies contain chloramines), organic and other contaminates in source water (ponds, lakes, well water, vandalism, etc.

This is the second year I have had chlorine demand, what do I do?

We recommend that if you have had a continuous problem with chlorine demands that you shock your pool weekly.

What level should I maintain my chlorine?

You need to maintain enough chlorine in the pool to control the amount of bacteria. It is recommend you keep a free available chlorine residual between 1ppm - 3ppm.

How often should I shock my pool?

You need to shock your pool at least every 2 weeks in the summer. Depending on the usage and weather.

How long should I wait to go into a pool that is sanitized with chlorine after I shock?

Wait until the chlorine level drops below 3ppm. Usually if you shock in the evening, the chlorine level will drop to 3 ppm

What is pH Increaser?

Raises the pH in pool water to guard against skin and eye irritation, corrosion of metal fixtures.

What is pH Decreaser?

Lowers the pH in pool water to prevent scaling, cloudy water and reduced effectiveness of chlorine. It is safer to store and use.

What is Total Alkalinity?

Raises Total Alkalinity to control pH bounce, staining of surfaces and corrosion of pool equipment.

What is acid rain?

The term "acid rain" refers to any precipitation that has a pH of 5.5 or lower and can be in form of rain, sleet, snow, or fog. It is estimated that half of the acid rain formation is caused by man-made factors, such as vehicle and industry emissions. The other half is attributed to natural causes, such as forest fires and lightening. These emissions form sulfuric acid and nitric acid when exposed to moisture and sunlight and fall as acid rain.

What effect does acid rain have on my pool?

Natural rain has a pH of 6.0, and acid rain has a pH of 5.5 or lower. As rain becomes more acidic, the total alkalinity of your pool decreases. Regular testing and adjusting of total alkalinity and pH will help protect against acid rain.

What is Chlorine?

Chlorine is a very aggressive and efficient disinfectant that kills bacteria. It is very important in maintaining pool water for swimmers safety and health. Over 90% of all pools (commercial and residential) use some form of chlorinating products as a sanitizer. Bacteria and algae enter the pool every day from sources ranging from bathers to the weather. So every day you have to fight bacteria and algae with sanitizers and algicides.

What is ppm?

Parts per million is a unit of measure used in measuring chemical application. It indicates that amount, by weight, of a chemical in relation to one million parts, by weight, of water.

What is pool water testing?

Pool water has chemical characteristics that must be measured regularly. Pool owners need to check two of these characteristics on a regular basis. pH. and Sanitizer. When these two factors are maintained within specified ranges, your pool water is probably not going to experience problems. By testing your pool water on regular basis, it will help you understand how bather load, weather conditions and chemical applications affect the water. We recommend you have your pool water professionally tested a minimum of twice yearly as they perform a more comprehensive set of tests. This will ensure that all the important parameters are in balance. Pools that are maintained in the proper test ranges will be protected from uncontrolled bacteria growth, be comfortable to the eyes and skin of swimmers, be less aggressive to pool surfaces and equipment, protected from growth of algae and most important be clear, sparkling and inviting to swimmers.

What is chlorine stabilizer?

Chlorine stabilizer is an organic compound that protects chlorinating products from the sun. It is also known as Cyanuric Acid and is sometimes referred to as "conditioner." Pool water that is stabilized offers pool owners a definite advantage over unstabilized pools. For instance, every 35 minutes a pool is exposed to the sun, the water will lose half of the HOCI present (which is the killing power form of chlorine.)

When do I add chlorine stabilizer?

Pool owners using unstabilized chlorine products to sanitize their pool can extend the life expectancy and efficiency of their free available chlorine residual by adding Aqua Clear Chlorine Stabilizer to outdoor pools. Indoor pools are usually not exposed to UV rays of the sun and, consequently, do not require the use of stabilizer. Initially, you should add enough Chlorine Stabilizer to achieve 40 ppm. When Cyanuric Acid levels drop below 30 pppm, stabilizer should be added. However, a pool being maintained on stabilized chlorinating products will constantly have a replenishing source of stabilizer being fed to the pool as the stabilized product is dissolved into the water.

What type of chlorine sanitizer do you recommend with the use of chlorine stabilizer?

Rather than continuously adding stabilizer, most pool owners prefer the convenience of a sanitizer that contains both a chlorinating product and a stabilizer. We recommend the use of Aqua Clear Aqua Tabs or Aqua Clear Rapid Chlor-56. Aqua Tabs strong chlorine formula dissolves slowly and completely. Rapid Chlor-56 is not as strong and dissolves faster. Because it dissolves so fast, when it's used as a primary sanitizer, it is usually and fed into a pool. More often, dichloro is used to provide a quick stabilized chlorine residual to boost a pool with heavy bather load or to oxidize waste or kill algae.

How do I add chlorine stabilizer to my pool?

To add 40 ppm of Aqua Clear Chlorine Stabilizer, add 1 pound of Chlorine Stabilizer for every 3,000 gallons of pool water, for 30 ppm add 1 pound per 4,000 gallons. Slowly add the appropriate amount of Chlorine Stabilizer granules through the skimmer with the pump running. Allow the pump and filter to run at least 24 hours. DO NOT BACKWASH the filter for 48 hours after product application. Stabilizer dissolves very slowly (which is why the skimmer application method is preferred) and if the filter is backwashed too soon after application, the Chlorine Stabilizer will be washed out of the filter before it has a chance to dissolve. We recommend a minimum level of 30 - 40 ppm. 30 - 200 ppm is an acceptable range. The maximum level of CYA in commercial pools is a established by local health departments.

How much is too much stabilizer?

A common myth in the pool industry claims that too much Stabilizer (Cyanuric Acid, CYA) in pool water "locks-up" the free available chlorine residual. Chemically, this is not accurate. The free available chlorine residual kills microorganisms with CYA levels up to 500 ppm. Minimum CYA level is 30 - 40 ppm, acceptable is 30 - 200 ppm for residential pools.

How do I lower Cyanuric acid (stabilizer) in my pool?

The only way to lower Cyanuric acid level is to partially drain your pool, then refill it with fresh water. Please contact your nearest pool dealer before attempting to drain any pool. If this procedure is not done properly, you could damage your pool.

How do I winterize my pool?

Once you have your pool balanced, add the correct dosage of winter shock and winter algaecide. To add additional protection to your pool's structure, finish by adding a chelating agent, such as AquaClear IronOut Formula II to keep minerals from dropping out and onto the pool's surface in cold temperatures. There are also a variety of winter products and accessories.

POOL AND SPA LAWS/REGULATIONS:
The following are additional guidelines to be followed during the start-up period:
As plaster cures, especially during the first 30 days, it is important to remove plaster dust in a timely manner by brushing and to stabilize water chemistry in the pool. Since chemicals can have a significant impact upon the life of your plaster it is suggested that only persons trained in this introduce chemicals to the pool. A re-plastered pool must be brushed at least twice per day until there is no longer visible plaster dust churned up by the brushing. Inadequate brushing may result in the plaster dust becoming permanently affixed to the surface of the pool. Pebble pools require limited brushing.

Start the pool equipment once the pool has been filled. Run the filter 18 hours a day for at least a week subsequent to plaster. Make sure that there is main drain suction to filter the dust from suspension in the water. Monitor filter pressure as the filter may need cleaning during this period due to the accumulation of plaster dust.

Do not swim in the pool until there is no longer evidence of plaster dust in the water and chemicals have been balanced.
Do not use the pool sweep cleaner for at least 21 days subsequent to the application of plaster.
Do not turn on the heater for at least ten days and longer if the pool is not in chemical balance.

INFORMATION: Ph Maintenance, filtration, brushing and water balancing are all essential to maintaining a smooth clean finish that will last for years. Plaster is, however, made from reframed materials applied under conditions beyond our control and is seldom blemish free. No two pools ever look the same. Air temperature, wind, moisture, and exposure to direct sunlight affect all phases of construction and therefore, the finished ‘look’ of your pool. You may notice anyone of the following conditions. These are not considered a deficiency in materials or workmanship: Surface checking and crazing-Cement shrinks as it cures. These do not leak, and are usually to ‘tight’ to require patching. More noticeable in colored plaster.

Discoloration:
Brownish-Usually organic from dust/dirt
Greyish-Usually calcium deposits. ALL POOLS have some calcium deposits. Keep to a minimum by adhering to 2, 3, and 4 above.
  • Dark spots or blotches on colored plaster-This is the original color of the plaster-Plaster without any calcium deposits on it.
  • Dark specks in colored plaster-Inherent in cement pigments.
  • Mottling-Blotchy, cloudy, or discolored wavy look-caused by the curing process of cement.
  • Plaster feels rough throughout the pool-Due to chemical imbalance or improper brushing.

Swimming Pool Chemistry

STEP 1:
Sanitizers: Main Source Use Poolife MPT Extra Tablets fed through a 4 lb. floating chlorinator to maintain a consistent 2.0-3.0 ppm free, available chlorine level.
STEP 2:
Additional Source Use Poolife chlorine shock every 7 - 14 days in the summer and every 30 days in the winter. More frequent shocking may be needed in periods of heavy use, extreme heat, or rainy seasons. You can also use it to raise low chlorine level quickly. Normal dosage is 1 lb. per 10,000 gallons. Add in the evening for best results.
STEP 3:
Preventative Algaecide Use Poolife Defend + regularly to prevent algae growth year round. In order for preventative algaecide to be effective, it must be added in sufficient quantity before algae has formed and the level must be maintained. Initial dose must be 8 to 12 oz. per 10,000 gallons of pool water, followed by a maintenance dose of 4 to 8 oz. per 10,000 gallons every week. Additions should be made directly to the pool the day after shocking.

Endure/Pool Proof: Sodium Tetraborate
Endure/Pool Proof is a wonderful addition to any pool chemical treatment program that provides brilliant, sparkling blue water, reduces skin and eye irritation, reduces chlorine consumption, and virtually eliminates algae growth. The recommended level for Endure/Pool Proof is 70 ppm.
The initial dosage of Endure required is 45 lbs. of Endure per 10,000 gallons, along with 3.5 gallons of muriatic acid per 10,000 gallons. The preferred method of addition is to broadcast ½ of the amount of Endure over the pool surface, then add ½ of the amount of muriatic acid into the pool; you will then need to brush the product around until it is dissolved. Repeat this process the following day. Periodic additions of small quantities to maintain the 70 ppm level will result in even more noticeable results.
The initial dosage of Pool Proof required is 7 Gallons of Pool Proof per 10,000 gallons. No additional acid is required. Be sure to shake the container vigorously to get all of the product out of the container.

 pH AND TOTAL ALKALINITY pH: Recommended level is 7.4 - 7.6 : pH is the measurement of how acidic or basic the water is.
If pH is too low (7.2 or below): This causes corrosion, etching, chlorine loss and eye and skin irritation. To raise pH use Poolife pH Plus. Follow the container directions to calculate proper amount to add. Poolife pH Plus should be broadcast over the pool’s deep end and brushed, unless the pool is 4’ deep or less. In shallow pools, it is better to predissolve in water.
If pH is too high (7.8 or above): This causes scale, cloudy water, chlorine inefficiency, eye irritation and clogged filters. To lower pH use muriatic acid or Poolife pH Minus. Follow the container directions to calculate proper amount to add. Muriatic acid should be added directly to pool's deep end with pump running, away from skimmer or in light, diluted amounts. Be very careful not to allow splash-up. Poolife pH Minus should be added directly to pool; brush until product dissolves.

Total Alkalinity: (Recommended Level: 80 - 120 ppm for all pools)
This stabilizes the pH. It is a measurement of the alkaline in the water that acts as a buffering agent, preventing big changes in the pH and avoiding corrosion and staining.
If the total alkalinity is too low (below 80 ppm for all pools): Raise with Poolife Alkalinity Plus at the rate of 1 ½ lbs. per 10,000 gallons for a 10 ppm increase. (Always raise to the highest ppm of the recommended range). Poolife Alkalinity Plus is always broadcasted directly over pool surface, with the pump running.
NOTE 1: Raising total alkalinity may also slightly raise pH.
NOTE 2: High cyanuric acid levels may affect total alkalinity test results. If cyanuric acid test results (see below) are above 100 ppm, water must be brought in to a Dolphin retail location for proper testing.

CALCIUM HARDNESS
Calcium Hardness: (Recommended Levels: 200-500 ppm for chlorinated water.
If the calcium hardness is too high (Over 500 ppm): This causes scale, cloudy water, rough surface, discoloration and reduced circulation. Add Poolife Stain Stop according to label directions when level is getting high or drain significant amounts of old pool water (1/2 - 3/4) and refill with fresh tap water.
If the calcium hardness is too low (below 200 ppm for plaster pools or 300-350 ppm for Fiber-Tec pools): This causes etching, pitting, pores for algae, corrosive water and rough surface. Add Poolife Calcium Plus at the rate of 1 lb. per 10,000 gallons to raise the calcium hardness level 10 ppm. It should be broadcast over the pool surface and undissolved granules should be brushed.

NOTE: In newly plastered pools calcium can increase 50 - 75 ppm as plaster cures.
3CYANURIC ACID
Cyanuric Acid: (Recommended Level: 40 ppm minimum).
This is a chlorine stabilizer and protects from chlorine loss due to the sun. Add Poolife Stabilizer and Conditioner at the rate of 3.5 lbs. per 10,000 gallons to raise approximately 40 ppm. It should be added very slowly through the pool skimmer with the pump running. The pool filter should be clean.
NOTE 1: The filter cannot be backwashed for 48 hours after adding Poolife Stabilizer and Conditioner.
NOTE 2: Stabilized chlorine tablets add cyanuric acid as they are used, but most other sanitation chemicals or systems require periodic additions to maintain the proper level.

METALS
Metals: Copper and Iron (Recommended Level: 0 ppm)
Add Poolife Intensive Stain Protection when chlorine is below 1.0. If pool water contains metals use 1 quart of Poolife Intensive Stain Protection per 10,000 gallons per 1.0 ppm of copper. (*Maximum 3 quarts per 10,000 gallons). Poolife Intensive Stain Protection should be added 7 days prior to super chlorination or shocking. If copper/metals levels are over 5 ppm, Dolphin recommends changing the water.

WATER TESTING TIPS
1. Have long-term water chemistry checked, such as copper, iron, calcium hardness, TDS, and stabilizer 4 times a year.
2. Take the water sample at elbow length and away from skimmer and return lines.
3. Replace solutions each spring and store out of the sun.
4. Compare test against a white background (plastic card).

IDEAL CHEMICAL RANGES
Free chlorine 2.0 - 3.0 ppm
pH 7.4 - 7.6 ppm
Total alkalinity - all pools 80 - 120 ppm *Always adjust to high end of range. Also see notes on page 2 regarding a high cyanuric acid level’s effect on total alkalinity test results.

Cyanuric acid 40 - 100 ppm
Calcium hardness - plaster 200 - 500 ppm
Calcium hardness – Fibre Tech 300 - 500 ppm

T.D.S. (total dissolved solids) 1000 ppm or below
Copper and iron 0 ppm
Endure/Pool Proof 70 ppm 4

Note 1: For bromine pools the above ranges apply, except no stabilizer is needed.
Note 2: For pools with salt generators you will need 3000-3500 ppm salt and 80 ppm cyanuric acid.
Note 3: Ionizers are machines that disinfect with copper and silver ions. These devices can be used to supplement your normal chlorine sanitizer, but not to replace it. Check the manufacturer's instructions for specific instructions on other water balance guidelines.

WATER-TESTING PROCEDURES (Providing copper, iron, calcium, and TDS are within range.)
1. Test total alkalinity weekly and increase with Poolife Alkalinity Plus.
2. Daily test pH and adjust in the range of 7.4 to 7.6.
3. Test free chlorine daily and maintain at 2.0 - 3.0 ppm using Poolife MPT Extra tablets in a 4 lb Floating Chlorinator. Super-chlorinate or shock with chlorine shock every 7 to 14 days in the summer (or 30 days in winter) or anytime chlorine drops below 1.0 ppm.

Note 1: When correcting chemical balance, do so in this order:
1. Metals - copper and iron
2. Total alkalinity
3. pH
4. Cyanuric acid
5. Calcium hardness
6. Chlorine

DO'S AND DON'TS:
DO'S
1. Do maintain correct water level (usually middle of tile).
2. Do shut off heater 10-15 minutes before pump (to allow to cool down).
3. Do replace broken pump and skimmer basket and broken skimmer weirs.
4. Do disassemble and clean D.E. filters at minimum of once a year.
5. Do check freeze guard operations at first freeze.
6. Do run pump continuously during freezing weather.
7. Do cap off chlorinators during freezing weather.
8. Do keep chemical container lids tight.
9. Do store chemicals in a cool, dry place with good ventilation. Chemical fumes can rust metals.

DON'TS
1. Don't vacuum large debris through skimmer.
2. Don't run pool cleaner without main pump on.
3. Don't leave anything on top of the heater (this is a fire hazard and can cause damage to the heater from it running too hot). 4. Don't mix any chemicals.
5. Don't add water to chemicals. (Always add chemicals to plenty of water.)
6. Don't store liquid chemicals on top of dry chemicals

Pool and Spa Safety Act

THE POOL & SPA SAFETY ACT

The Virginia Graeme Baker Pool & Spa Safety Act (P&SS Act) was enacted by Congress and signed by President Bush on December 19, 2007. Designed to prevent the tragic and hidden hazard of drain entrapments and eviscerations in pools and spas, the law became effective on December 19, 2008.

Under the law, all public pools and spas must have ANSI/ASME A112.19.8 performance standard, or the successor standard ANSI/APSP-16 2011 compliant drain covers installed and a second anti-entrapment system installed, when there is a single main drain other than an unblockable drain.

WHO IS VIRGINIA GRAEME BAKER?

Learn more about the young girl who inspired the Virginia Graeme Baker Pool and Spa Safety Act.

The Virginia Graeme Baker Pool & Spa Safety Act (P&SS Act) takes its name from Virginia Graeme Baker, a young girl who drowned after she was trapped under water by the powerful suction from a hot tub drain.

A twin and the youngest of five, 7-year-old Graeme, as her family called her, was the daughter of Nancy and James Baker IV, the son of former Secretary of State James Baker III. A member of her community swim and diving team, Graeme was able to swim without assistance since she was 3 years old.

In June 2002, Graeme became stuck to a hot tub drain and was unable to pull herself free. Efforts by her mother to pull Graeme from the drain proved unsuccessful. Two men who eventually freed Graeme from the spa pulled so hard that the drain cover broke from the force. Graeme died from drowning, but the real cause of her death was suction entrapment due to a faulty drain cover.

After her tragic death, her mother, Nancy Baker, worked tirelessly to advocate for pool and spa safety. Mrs. Baker, her family and Safe Kids Worldwide actively lobbied Congress to win support for a law to require anti-entrapment drain covers and other safety devices, as needed. The statute, which was sponsored by U.S. Rep. Debbie Wasserman Schultz of Florida, was signed into law by the President in December 2007.
