How much warmer will my water get? Our solar covers will raise water temperature up to 15 degrees fahrenheit! Does the cover’s color matter? Blue solar covers are effective in trapping heat and conserving chemicals. When pool water is properly balanced their color resists fading. How does my solar cover heat my pool? Solar covers are made of thermal bubbles that capture the sun's UV rays to create and retain heat naturally. It is important to the bubble side down into the water to work effectively. How do I trim my solar cover to size if I have extra material? Our solar covers allow for trimming to ensure a perfect fit whether your pool is round, oval, rectangular or even a unique shape! Do your covers work with solar reel systems? Our solar covers will fit most solar reels. While a reel isn’t required for a solar cover, it makes removal and positioning easier.
