Use the complete line of Blue Wave Pool Chemicals to simplify pool care and make your water sparkle. Note: 1 lb. treats 10,000 gallons.
These powerful 1 lb. bags of Blast Out® Pool Shock by Blue Wave are your secret to a successful pool season! Swimmers, rainfall, sunlight, and leaves deplete the ability of your pool chlorine’s ability to sanitize. Shock "burns" or oxidizes these contaminates and replenishes the chlorine level in your pool. Shocking actually restores your pool 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 usable pool chlorine to oxidize the organic matter. Blue Wave pool shock is the solution!!

For a trouble-free pool season remember to shock:
  • Once every other week under normal conditions
  • Once a week during prolonged periods of warm weather, heavy rainfall, and heavy swimmer loads

Dosage: 1 lb. treats 10,000 gallons.
