SpaGuard's pH Increaser provides spa owners with a quick-dissolving granular formula to raise dangerously low pH levels, preventing costly damage to spa plumbing, fixtures, and surfaces as well as provide a much more comfortable water supply for bathers. pH Increaser slowly raises pH levels to ensure accurate calculations to get the desired level. Your spas sanitizer will also operate better when not on the extremes of the pH scale, improving water quality.
