Cal-Hypo Shockwave 68% Granular Shock, Case of 12 1 lb Bags

A full case of twelve 1 lb bags of Shockwave 68% calcium hypochlorite granular shock, with 65% available chlorine. This is the same fast dissolving Super Shock formula, packaged by the case so you have a season of weekly treatments on hand.

Dosing

Each bag treats 10,000 gallons. Use one bag for a 10,000 gallon pool, two for 20,000, and so on. Single dose bags mean no measuring and no half used containers to store.

What it does

Cal-hypo shock delivers a rapid chlorine boost that clears algae, bacteria and other contaminants. Use it after heavy bather loads, after storms, or as a regular weekly shock to keep the water clear.
