Natural Chemistry 07100 Spa Swimming Pool COVERfree Barrier Layer - 32oz Each;

COVERfree's advanced one molecule thick monolayer technology offers the ability to save water and money by decreasing evaporation. COVERfree forms on the water surface. Even when the water is disturbed by the wind, circulation pump, or bathers, COVERfree's technology remains at the surface to protect from heat loss and evaporation. Shake product vigorously. With circulation system running, add 4 oz. per 675 sq. ft. of surface area, assuming an average pool depth of 4 feet (20,000 gallons). Note: Skimmer application is preferred, however, COVERfree can be added directly to pool water. Important: Circulation system must be running for either application. 1 Buy = Two 32oz Bottles!
