Calcium Hypochlorite

Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water.

As a swimming pool chemical, it is blended with other chemicals less on than other forms of chlorine, due to dangerous reactions with some common pool chemicals. In solution, calcium hypochlorite could be used as a general purpose sanitizer,[3] but due to calcium residue, sodium hypochlorite (bleach) is usually preferred.
