Robelle 12? x 24? Oval Heavy Duty 8 Mil Blue Solar Cover (Boxed)

Solar Covers are designed to collect heat from solar energy and transfer it to your pool water. These covers are made from a durable polymer material with thousands of air sealed bubbles. Solar covers float "bubble side down" on the surface of your pool water when the pool is not in use, allowing solar energy to pass through and trapping it as retained heat in the pool. The Heavy-Duty Blue Solar Cover will cut evaporation by up to 90%, decreasing your chemical consumption and saving you money, while the heat-retaining round bubbles increase your pool temperature up to 10 degrees. This cover comes with a 3-year warranty.
