These powerful 1 lb. bags are your secret to a successful swimming season! Swimmers, rainfall, sunlight, and leaves deplete chlorine's ability to sanitize your pool properly. Shock "burns" or oxidizes these contaminants and replenishes the chlorine level in your pool. Shocking actually restores your chlorine's "fighting power" and makes it safe to swim in your pool 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. Blue Wave shock is the only solution!

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
