Pools & spas are extremely vulnerable to illness causing bacteria, irritating chloramines and other contaminants introduced into the water by bathers and environmental factors. Cal-Shock, with 65% available chlorine, is designed to dissolve quickly and provide a ready source of available chlorine in swimming pools. When used according to directions, Cal-Shock kills bacteria, controls algae, and destroys organic contaminants. Always adjust pH between 7.2 and 7.6 prior to using Cal-Shock. Additional shocking to keep water clean and clear is needed after rain and heavy winds, high number of swimmers, increased water temperature, and/or increased frequency of pool usage.
