Did you know?

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
