pH Minus by O-ACE-sis is granulated sodium bisulfate. High pH above 7.8 causes scaling, calcium deposition and cloudy water in pools. Fast dissolving granular pool acid lowers the pH and alkalinity of pool water. Safer to handle than muriatic acid. 2.5 lbs of pH minus is equivalent to 1 qt of muriatic acid. Low cost and easy to use. Works continually to kill bacteria.
