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.
