These powerful 1 lb. bags 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 contaminants and replenishes the chlorine level in your pool. Shocking actually restores your chlorine's "fighting power" and makes it safe to swim again.

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
