Shockwave 68% Cal-Hypo Granular Shock, Case of 6, 1 lb Bags

Shockwave Super Shock is a fast dissolving granular pool shock: 68% calcium hypochlorite with 65% available chlorine. This case holds six 1 lb bags.

Simple dosing

One bag treats 10,000 gallons, so there is nothing to measure. Open a bag, add it to the pool, and the chlorine boost goes to work on algae, bacteria and other contaminants.

Six bags is enough to shock a 10,000 gallon pool six times, or a 30,000 gallon pool twice. Keep the case on hand for a weekly shock or a fast recovery after heavy use or a storm.
