Description
Granular product adjusts water pH and alkalinity down. Provides a greater amount of control for large and commercial spas. 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 – 7.8. High pH (above 7.8) can cause scaling and/or cloudy or colored water.
