Instead of getting technical and trying to teach a science class explaining how enzymes work we will try to break it down more simply. Enzymes break non-living things down to smaller and smaller bits. Many non-living things are in pool and spa water; body oils, sweat, cosmetics and sunscreens to name a few.
SMARTZymes contain thousands of enzymes with the potential to break down thousands of different non-living waste products in your water.

Natural Chemistry pioneered the use of phosphate removal technology long before it was popular. High phosphate levels in pool water can create many water issues. Most people today are aware of the efforts by government agencies to limit the use of phosphates in common household products due to their effect on water. Natural Chemistry has a variety of phosphate removal products that have been proven to make water care easier.
