Lowers pH

Granular product adjusts water pH and alkalinity down. Provides a greater amount of control for large and commercial spas.  


  • Lowers pH and total alkalinity
  • Increases effectiveness of sanitizer

As Needed
1. Make sure all equipment is OFF.
2. Add 1/4 oz. (1-1/2 tsp.) to the spa water.
3. Turn on circulation system for 30 minutes.
4. Retest water. If pH is still above 7.8, repeat steps 1-3.

For best results, dissolve granular products first by adding to a small, plastic pail filled with water. Then, apply the solution to the spa water.
It is important to maintain the pH between 7.2 and 7.8. High pH (above 7.8) can cause scaling and/or cloudy or colored water.
