Having just the right amount of calcium is essential to the health of your swimming pool. Too little calcium will erode plaster, cause etching of pool surfaces, and accelerate corrosion. Suncoast® Chemicals Calcium Hardness Increaser raises the hardness level of your swimming pool water.
The ideal range for calcium hardness is 200 to 400 ppm. If your calcium hardness tests below the desired range when you use a water test kit, add Calcium Hardness Increaser. The application of 1.2 lbs. of Suncoast Chemicals Calcium Hardness Increaser in a 10,000 gallon pool will increase your pool water's hardness by 10 ppm. Calcium Hardness Increaser is available in 4-lb. and 8-lb. eco-friendly pouches and in a 25-lb. case box.
