SPAGUARD pH INCREASER raises the pH of water in spas and hot tubs. The pH should be maintained at 7.2 to 7.6 (as measured by an accurate test method). A low pH can cause eye irritation, strong chemical odor, rapid sanitizer loss and corrosion of metal in the filtration system.

Measurement and Dosing: 

Use all level measurements. 1 capful - 2 teaspoons; 3 teaspoons = 1 tablespoon.

Directions for use:

Read entire label and use strictly in accordance with directions and hazard statements.

1. Use an accurate test method to determine pH.
2. Determine the required amount of SpaGuard pH Increaser need to adjust the pH to maintain a reading of 7.2 to 7.6.
3. With the pump running on high speed, sprinkle the required amount of SpaGuard pH Increaser into the spa water and continue running pump for 30 minutes.
4. Restest pH and adjust as necessary.
