In The Swim pH Reducer for pools is safer to use to balance your pool water, is less corrosive and safer to store than muriatic acid, a common pH decreaser alternative. Our pH reducer for pools uses sodium bisulfate which lowers both pH and Total Alkalinity levels, with less skin and eye irritation, and won't damage pool soft and shiny pool surfaces.

Your pool water pH and alkalinity levels is very important to healthy pool water and proper pool surface protection. A high pH level in your pool water can cause staining, cloudy water, metal corrosion and even chlorine loss, while irritating swimmer’s skin and eyes. In The Swim granular pool pH reducer brings high pH levels (7.6 ppm and above) and high Alkalinity levels (120 ppm and above), back to normal levels safely and quickly for a more comfortable swimming environment.
