Calcium Hardness Up increases water hardness to prevent foaming, equipment corrosion, and scaling. This product is easy to apply, just pour it directly into the pool. It is compatible with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.

Dosage: 1-pound per 10,000 gallons of pool water will increase the calcium hardness 10 ppm. Directions for Use: Determine calcium hardness level; it should be between 150-250 ppm for spas and 200-400 for pools. If level is below 150 ppm for spas or 200 ppm for pools, add calcium hardness up by distributing product over the water surface.

Properly balanced water will prevent the formation of scale deposits and eliminate the corrosion of metal pipes and fixtures. Keeping your pool water balanced is an important step in getting the most out of and preserving the life of pool equipment.
