Calcium Hardness Increaser

In The Swim Pool Calcium Hardness Increaser

In the Swim Pool Calcium Hardness Increaser effectively resolves low hardness levels, preventing aggressive water behavior. When levels fall below 200 ppm, water extracts minerals from surfaces, causing etching and corrosion. Add the Increaser to raise levels to the ideal 200 - 400 ppm range. Contains 97% granular calcium chloride. Dosage: 6 lbs. per 10,000 gallons raises levels approx. 50 ppm. Do not premix or mix with small amounts of water, as it undergoes a chemical reaction generating heat.
