Solutions of NaOCl and NaDCC containing the same levels of available chlorine (av.Cl) exhibited very similar bactericidal activities, despite significant differences in pH. High levels of calcium in a pool, combined with high pH and high TA, can precipitate the calcium out of solution, causing milky water. Adding 10 ppm of available chlorine using calcium hypochlorite will add 8 ppm CH, according to APSP. Calcium hypochlorite is an attractive alternative to chlorine gas or sodium hypochlorite (bleach) solutions because it is a dry form of chlorine that offers several handling advantages.
