You work too hard to keep your pool clean for it to evaporate before your eyes. With the Lo-Chlor Aqua Blanket Liquid Pool Cover, you can decrease evaporation and increase your pool season. This liquid pool cover uses Monolayer Technology to modify the surface layer of your pool one molecule deep. The formula acts as a barrier for the pool water, dramatically reducing heat loss and evaporation. This means you can have warmer water and a longer pool season with lower energy costs. Biodegradable and safe to use for all pool surfaces, this formula cannot be felt, seen, smelt, or tasted. To use, simply add 3 ounces per 500 square feet of water surface (15,000 gallons) per week. It's really that easy to preserve your pool. Bask in the benefits of a physical cover while enjoying the beauty of your crystal clear pool with the Aqua Blanket Liquid Pool Cover from Lo-Chlor.
