GLB PH Down Balancer (2.5# Pouch) #GLB-71252A

GLB PH Down lowers the pH level in swimming pool water. This product aids in preventing staining, scaling, and clouding of pool water. Sanitizers work most efficiently when pH is kept in proper range. Therefore a properly balanced pool will require less sanitizer and less pool maintenance. Keeping your pool water balanced is an important step in getting the most out of and preserving the life of pool equipment. PH Down can be used with chlorine, bromine, ozone, biguanide sanitizers, and salt water pools.


  • Sodium Bisulfate: 95%, Inert Ingredients: 5%


  • The most efficient and economical use of chlorine is obtained when the pH of the water is maintained at all times between the values of 7.2 and 7.8. Between these two levels, eye irritation will be reduced to a minimum and equipment life will be prolonged.
  • When the pool water pH value is above 7.8, as determined by the use of a pH test kit, add 4 oz. (1/4 of a pound) of GLB pH Down while pump is in operation for each 10,000 gallons of water by distributing it into the deep end of the pool (but not near metal fittings or the skimmer).
  • Allow 6 to 8 hours for distribution of the chemical throughout the pool, then recheck the pH.
