Dazzle Assure uses a 3-tier strategy to make maintaining your pool simpler, easier and friendly; 1) a natural concentrated enzyme digests organic matter for deep water cleaning, 2) a powerful anti-phosphate product removes algae food from the water to provide control, and 3) a clarifier powerful sure to polish your water to sparkling clarity. All of this is in a concentrated formulation so you use as little as possible. Improved and recommended formula in step 2 of the PureWoW swimming pool maintenance system.
