Calcium Increaser (calcium chloride) is used to raise the hardness level which has a recommended range of 175-300ppm. Low hardness, or calcium levels, can cause plaster etching, corrosive water, surface pitting and premature equipment failure. Calcium Increaser is essential in soft water areas or when pools are being filled through a water softener. Excessive foaming is also a symptom of soft water.
Available in 4 and 25 pound buckets
