* Chlorine solution is prepared by mixing 1 lb calcium hypochlorite (65%) with 8 gal of
water or diluting 10% sodium hypochlorite 1 gal with 9 gal of water. Five percent
chlorine solution is prepared by mixing 5 lb calcium hypochlorite (65%) with 8 gal of
water or dilution 10% sodium hypochlorite 1 gal with 1 gal of water.
