Q:Why does my plaster have stains?A:Some minor discoloration is normal in new plaster.However, actual staining can be caused by the following: the pH is too low;the total alkalinity level is too low;the calcium hardness level is too low;the level of total dissolved solids is too high;high levels of metals in your water.

Stains can also be caused by debris left in the pool. Usually, metals escaping from this debris create a deposit on the pool plaster and this creates discoloring. Items such as a leaf from a tree, if left long enough on the pool floor, can stain your plaster. 

Q:How do I eliminate plaster stains?A:Stain removers and acid washing are two examples of how to remove plaster stains. However, a pool service professional in Scottsdale, AZ should be consulted before any stain removal is attempted. The use of a stain remover and/or an acid washing should always be performed by a pool service professional in Scottsdale, AZ.
