Dazzle Assure uses a 3-tier strategy to make pool maintenance simpler, easier and more friendly; 1) a concentrated natural enzyme digests organic matter for a deep clean, 2) a powerful phosphate remover removes algae food from the water to ensure algae control, and 3) a powerful clarifier ensures your water is polished to sparkling clarity. All in a concentrated formulation so you use as little as possible. Improved formula and recommended as Step 2 of the PureWoW Pool Maintenance System.
