5 lb. pH increaser
pH INCREASER Use as needed to raise the pH level to the ideal range of 7.2 to 7.6 ppm. Slows the rapid loss of chlorine caused by low pH, and slows chlorine dissipation, so your pool uses less chlorine. Stops eye irritation, etching and corrosion caused by low pH. Contains sodium carbonate "soda ash". Recommended dosage: 1 lb. per 10,000 gallons.
