Calcium Hypochlorite is 73% available chlorine and is quick dissolving. It is a routine sanitizer that kills and prevents the growth of algae, bacteria and other microorganisms. Widely used as a shock treatment to destroy organic contamination in pool water, thereby improving the water clarity.
Strong calcium hypochlorite solutions serve as disinfectants for cleaning pool sides and bottoms, decks, diving boards, ladders, floats, locker and shower room floors and benches, sinks and toilets. Restores crystal clarity to pool water.
Dosage: 1 lb. raises 80,000 gallons of water 1 ppm. Use to shock the water weekly. It is recommended to shock your pool more frequently after heavy rain, hot weather, and when bather load increases heavily.
Note: Also referred to as pink or red slime, this bacteria is brushed away and quickly returns where it collects around ladders, skimmers, lights, pool walls at the water line, steps and plastic surfaces. Brush areas thoroughly to remove slime, and apply Zappit 73.
