Calcium Deposits On Pool Tile
Calcium Deposits on tiles is caused by the water being out of balance. Scalling can be caused by High pH, High Calcium levels or both, Causing the calcium in the water to settle out on the pool surfaces. The water would be described as Scalling.
The first step is to adjust the ph of the Pool to an acceptable range of 7.2-7.8, if the calcium level is very high (> 400 ppm) you should try to adjust the ph to the lower end of this range or use a sequestering agents. In extreme cases you might need to replace all or part of the water to reduce the calcium level. Test the incoming water versus the pool water to make sure you are adding water low in calcium.
Removal of Calcium from tiles and similiar surfaces is done by brushing on a 1 part Muriatic acid to 3 parts water. Use goggles and gloves when handling Muriatic Acid |
