pH Reducer Granules

pH is a measure of how acidic or how alkaline (not to be confused with total alkalinity) the water is.

The pH scale is 0 to 14, with 0 being very acidic and 14 being very alkaline. pH 7 is neutral and for pools the pH should be maintained between 7.2-7.6, this being slightly alkaline protects the pool and plant room equipment from aggressive, corrosive water and is comfortable for bathers.  Our pH Reducer Granules will lower pH levels in your swimming pool or hot tub water.

pH below 7.2 will cause:

  • Corrosive water
  • Etching of surfaces
  • Staining
  • Skin & Eye Irritation
  • Damage to plant room equipment

pH above 7.6 will cause:

  • Scale formation
  • Filter calcification
  • Cloudy water
  • Drying to skin
  • Reduced effectiveness of chlorine
