Transparent Black Solar Cover 21 ft. Round 12 Mil

Our solar covers are made of durable resin and have thousands of tiny air bubbles designed to capture and transmit solar heat to your pool. A solar cover will keep your pool water cleaner by blocking out dirt and debris which will save on chemicals. Using a solar cover cuts water evaporation by up to 95% and prevents heat loss. The solar cover also takes advantage of the suns "free heat" that will result in, on average a 15° temperature rise.
