Sun2Solar Blue 21-Foot Round Solar Cover | 800 Series Style | Heat Retaining Blanket for In-Ground and Above-Ground Round Swimming Pools | Use Sun to Heat Pool Water | Bubble-Side Facing Down in Pool

#ad
Sun2Solar #ad - Assure your pool’s temperature does not drop too much by protecting it at night through use of a solar blanket. Heat retention - after everyone has called it a day with wrinkled fingers from too much fun in the sun, make sure to place this solar cover back atop the water. Trim to fit - your pool may be uniquely shaped and getting the right fit is as easy as finding a marker and sharp pair of scissors.

When not enjoying a refreshing swim, keeping your pool covered lessens the vast amount of water lost into the environment. Enter the swimming pool confidently knowing the Sun2Solar solar cover has kept the water warm just for you. Attractive blue design - sun2solar solar blankets are made from a film of thousands of tiny bubbles, which work together to collect and retain heat both at night and on those chilly days. Have the bubbles facing down to the water and trace a line on the cover showing where you should cut off the additional material.

It’s easy to put on and take off allowing more time for showing off. Fill up your swimming pool less and enjoy it more! Jump into warmth - show friends and family your bravery by jumping in without the standard toe dip. Don’t lose all of that warmth generated throughout the day when the sun sets. Minimize water evaporation - the use of a solar cover helps in preventing up to 95% of pool water evaporation. The blue color provides an appealing look while also using the sun’s rays to help warm your swimming pool.
