A good breeding ground for bacteria is not the only problem created by oils and other bather introduced debris. The build-up of scum and debris can also turn the water cloudy and foamy. Enzyme Cleaner can help. Natural enzymes create a chemical reaction with the oils in the scum line. These enzymes actually break certain bonds in the oils. This transforms the oils into harmless hydrocarbons. Enzyme Cleaner is constantly working to eliminate oils and lotions and give spa owners the following benefits: The spa does not smell bad, The water is clear instead of cloudy, The filter does not have to work as hard and Less work at keeping the water line cleaned.
