This product is used to raise the calcium hardness in pool water. Low calcium hardness may cause pool water to be corrosive which may result in staining, etching or distorting of all types of pool surfaces. Surface etching by low calcium hardness will become more abrasive and uncomfortable for bathers. Rough surfaces also increase problems with algae and makes cleaning more difficult.
