A compound of chlorine and calcium used in white granular or briquette form as a bactericide, algaecide and oxidizer in water treatment.
This is a form of Chlorine sanitizer in powder or granular form. It contains 65% available Chlorine and is unstabilised. Because of this it is suitable for shock chlorination where you need to get a lot of Chlorine into the water quickly. Also, if the use of stabilized Chlorine has built up too much stabilizer in the water, Calcium Hypochlorite can be used as an alternative. Because it contains Calcium, it will raise the Calcium hardness of the water. This can be a good thing if you are trying to raise the hardness in a soft water area or it can be undesirable if you have too much Calcium and it is causing scaling problems. As it is alkaline, Calcium Hypochlorite will raise the pH of the water.
