GLB Calcium Hardness Up Balancer (6# Bottle) #GLB-71210A

GLB Calcium Hardness Up increases water hardness to prevent foaming, equipment corrosion, and scaling. Keeping your pool water balanced is an important step in getting the most out of and preserving the life of pool equipment. This product is easy to apply, just pour it directly into the pool. This product is compatible with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.


  • Calcium Chloride: 94%, Other Ingredients: 6%


  • Maintenance of the proper calcium hardness in pool water is an important part of maintaining overall water balance. Properly balanced water will prevent the formation of scale deposits and eliminate the corrosion of metal pipes and fixures.
  • Using a suitable test kit, determine the calcium hardness level. In general, the calcium hardness level should be 150 ppm to 250 ppm. If the level is below 150 ppm, add GLB Calcium Hardness Up by distributing the product over the water surface. One pound of GLB Calcium Hardness Up will increase the calcium hardness 10 ppm per 10,000 gallons of water.
