Dazzle's pH Minus lowers pH and Total Alkalinity. A fast-dissolving, highest quality granular formulation, it safely lowers levels when compared to more toxic and dangerous liquid acids.  Quality matters with balancing products so they don’t introduce unwanted impurities. A balanced pH prevents corrosion and scale-formation, allows sanitizers to work more efficiently, prevents cloudy water and is largely responsible for the overall comfort of the water.
