The water in your swimming pool needs to be balanced in order to prevent any problems such as pool chemical residue or harmful pool chemical reactions. Unbalanced pool water can also produce scale formation on the surface of your swimming pool.
Scale formations appear as flakey white deposits on the pool surface and are a result of one or more unbalanced pool chemicals. Scale deposits not only make a pool surface unattractive, unsanitary and rough-feeling, but also reduce water circulation through the pool filter and pool plumbing system.
If scale formations in your pool are very noticeable on the pool surface, the pH, calcium hardness, and total alkalinity must be tested with pool water test strips and adjusted immediately. Most likely one factor, if not all three, is much too high and needs to be reduced. If all three pool chemical levels are too high, you should adjust pH and total alkalinity first, since reducing calcium hardness is more difficult. Adjust pH levels to the ideal range of 7.2-7.6 and adjust alkalinity levels to the ideal range of 80-120.
When you are ready to adjust a high calcium hardness level, you should drain a significant portion of your pool water and replace it with fresh water that is low in calcium hardness and total dissolved solids. If the scale formations are in your spa or hot tub, you should drain all of the water out. If you don’t know how to determine the amount of fresh water you will need to put back in your pool, call 888-718-7946 for assistance.
Note: If high calcium hardness levels are a continuing problem, use a sequestering agent to prevent future scale formations on your pool surfaces.
