The all New Natural Chemistry Blue Print range for spa and hot tubs

Spa pH Decreaser

Decrease pH level to ideal range

Natural Chemistry's SOAK 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 readily.


 Directions for use: Read the entire label before using.

  1. Test spa water for pH level.
  2. Compare pH test results to chart below to determine appropriate amount of product necessary to make adjustment.
  3. With the spa not in use and circulation pump operating, add required amount directly into spa water. Continue circulating water a minimum of 30 minutes.
