Pool Perfect Commercial AF reduces the buildup of non-living organic contamination and prevents its recurrence. Sunscreens, body oils, lotions, cosmetics along with other contaminants make up the non-living organic load that contributes to problematic symptoms such as: waterline rings, short cycling filters, unpleasant odours, poor water clarity, and peak load cloudiness. This concentrated naturally based enzyme formula works with all sanitizing systems. Pool Perfect Commercial AF contains naturally based enzymes, botanical extracts and other biodegradable ingredients. It's non-toxic, non-irritating, and it's environmentally friendly.
