To maintain the proper level of residual chlorine when bather load is heavy, shock your pool once a week with a 3 to 5 times higher than normal dose of chlorine.
Chlorine is broken down by the sun's ultraviolet rays. Using cyanuric acid to stabilize the chlorine in your pool at the beginning of the swim season will help you maximize your chlorine's efficiency all summer long.
Filters remove suspended particles from pool water, but don't control bacteria or algae. Maintain a residual chlorine level of 1.0-3.0 ppm (parts per million) to kill bacteria and/or algae present in the water. S.Merillat® |
