Purge attacks the root cause of most pool maintenance problems... the build-up of non-living organic waste contamination! Non-living organic contaminants like oils, lotions, sunscreen, cosmetics, hair products, and sweat are the underlying root cause of many pool issues. High non-living organic loads will cause cloudy water, hard to maintain chemical levels, clogged filters, foaming and nasty waterline rings. These contaminants collect and build-up in your pool circulation system and filter. By purging the pool of this non-living organic build-up, the symptoms of high non-living organic loading will be eliminated.
