Cal-Chlor Granules contain 65% available chlorine and 35% calcium and are highly effective at killing microorganisms and other contaminants to sanitize swimming pool water and to improve water clarityGet fast, hard-hitting results with Cal-Chlor Sanitizing Granules!

Cal-Chlor Granules are calcium hypochlorite sanitizing granules that are ideal for swimming pool shock treatments as well as for regular use. Containing 68% available chlorine and 35% calcium, these calcium hypochlorite granules can be used to quickly and effectively disinfect swimming pool and spa water. By killing bacteria and other contaminants, Cal-Chlor Granules help to maintain a healthy, safe and sanitized swimming environment free of potentially harmful microorganisms.

Cal-Chlor Granules will also help to improve and maintain water clarity for a beautiful, sparkling clear swimming pool. Cal-Chlor Granules should be pre-dissolved before they are dispensed into the swimming pool in order to ensure the best results possible. Pre-dissolving calcium hypochlorite granules will also help to prevent liner bleaching and reduce clouding of the water.

Please Note: Must dilute to prevent bleaching of the liner.
