If you are having issues with your pool not fully clearing up, cloudy and not holding chlorine....... we are seeing alot of issues with high phosphate levels. If you are holding. Chlorine and its just cloudy, you may need a floc treatment. So before you go to a store and they charge you an arm & a leg for all kinds of chemicals, have us test your water for phosphate & nitrates and we will steer you in the right direction
