Care Free is a proprietary multi-function water conditioning system exclusive to the Beachcomber line of products. Care Free replaces the traditional water sequesterant, oxidizers, enzymes, clarifiers and periodic shock treatments. It is designed to use in conjunction with Care Free Boost sanitizer. Care Free offers a low odor that is normally attributed to chlorine systems, due to its low chlorine use. With a pH of 2.5 and a blend of oxidizing compounds, Care Free removes organics in the water. This allows for less chlorine to be used. And what chlorine is used, can do its job more effectively.
