These powerful 1 lb bags of Cal-Hypo Pool Shock are your secret to a successful season! Swimmers, rainfall, sunlight, and leaves deplete chlorine’s ability to sanitize your pool. Shock “burns” or oxidizes these contaminates and replenishes the chlorine level in your pool. Shocking not only gets rid of all these contaminants, it also restores your chlorine’s “fighting power” and makes it safe to swim again.
Did you know that those noxious odors, skin irritations, and eye-burning problems are not usually the result of too much chlorine? In fact, there is likely not enough chlorine to oxidize the organic matter.
For a trouble-free season remember to shock:
-Once every other week under normal conditions
-Once a week during prolonged periods of warm weather, heavy rainfall, and heavy bather loads
