Item Details

Natural Chemistry Spa pH Decreaser

Natural Chemistry's Spa pH Decreaser lowers the pH of water in spas. Spa water should be maintained between a pH of 7.2 and 7.6. When pH is too high (above 7.6), water becomes uncomfortable to bathers, sanitizers lose their efficiency, water may become cloudy and scale forms more easily.


  • Decreases pH in spa/hot tub water
  • Helps with bather comfort and sanitizer efficiency
  • Granular formula


  • 3.37 Pounds
  • Sodium Bisulfate 91%
  • Spray Adjuvant 9%

Dosage Amounts:

  • Example; Add 1.5 tsp of this product in a 400 gallon spa if the pH is between 7.8-8.0.
  • Read entire label before using. Complete dosage chart can be found on the bottle.
