Use SPAGUARD pH INCREASER To Increase Low Levels Of pH. This Product Is Compatible With All Sanitizer Types.

***Note: Low pH Is Uncommon. It Is More Common For Alkalinity To Drift Low And Then Drag The pH Down With It. Chances Are If A Test Strip Indicates Low pH Yet Indicates That The Alkalinity Is Ok The Alkalinity Is Most Likely Low And Increasing The pH Won't Much In That Instance And It Is Encouraged That You Send In A Water Sample.

Label Directions For Maintenance And Dosing: Use all level measurements. 1 capful = 2 teaspoons; 3 capfuls = 1 tablespoon. Note: Container cap provides convenient measure. 

Label Directions For Use: Read entire product label and use in accordance with directions and hazard statements.

  1. Use an accurate test method to determine pH.
