That makes this the strongest granular shock you can buy. It quickly dissolves in your swimming pool to kill bacteria, algae, and other harmful contaminants. Maintaining proper chlorine is essential to keep your pool safe for swimming.

Cal-Hypo can be used as a maintenance product or treatment product. Pools that are prone to algae, debris, sunlight, and swimmers may require more frequent doses.
