This product produces crystal clear water through a 4 in 1 action. The rich green formulation combines a powerful clarifier, sequestrant, chelating agent, and flocculent in one convenient product. This product helps prevent scaling, staining, scum line buildup, and foaming in swimming pools and spas. This product requires no premixing, will not affect pH and is compatible with all swimming pool sanitizer systems. It is also useful in removing oils, soaps, metals, cosmetics, and other particulate matter that can cause staining, cloudy water and discoloration in swimming pools and spas. This product may increase filter efficiency. Initial Application: Clean or backwash the pool filter. Apply 1 oz. per 5,000 gallons of swimming pool water. With pump on and water circulating, apply product directly along the edges of the pool or broadcast over the surface of the pool water. For best results, allow at least 6 hours of pool circulation after applying. If water is cloudy or discolored after 72 hours, re-apply 1 oz. per 5,000 gallons of pool water, running pump continuously until clear. Maintenance Application: Apply 1 oz. per 5,000 gallons once every 2 weeks. This will keep your pool looking crystal clear.
