Round solar pool cover for 12 foot above ground pools. Color Blue. Size 12' round. Durable polyethylene bubble blanket that captures solar heat and reduces evaporation to keep your pool warmer and cleaner. Key benefits Efficient solar heating: Thousands of thermal bubbles capture and retain solar energy, raising pool water temperature by up to 10 degrees F in 5 to 7 days of consistent sunlight. Significant water savings: Helps minimize evaporation by up to 95 percent, reducing the need to refill and helping maintain chemical balance. Less cleaning and maintenance: Acts as a barrier against leaves, dirt, and debris so you spend less time skimming and use fewer cleaning chemicals. Durable construction: Made from sturdy polyethylene with a bubble design that provides reliable heat retention and long service life. fit: Sized for 12 foot round above ground pools and easily trimmed for a precise fit on different pool shapes. Performance and compatibility Function: Solar thermal cover designed to capture sunlight and retain pool heat while limiting water loss. Compatibility: Intended for round above ground pools with a 12 foot diameter; can be trimmed to match other shapes and sizes. Material: Polyethylene bubble blanket in blue color for effective insulation and sun absorption. Practical use scenarios Early spring or late fall: Extend the usable season by warming the water and slowing heat loss overnight. Windy or dry climates: Reduce frequent refills and chemical adjustments by cutting evaporation. During short trips away: Keep debris out and water loss to a minimum so the pool requires less attention on . Simple handling notes Lay the cover on the water surface to trap heat and reduce evaporation. Trim as needed for a snug fit; oversized covers can be cut to match pool shape. This 12 foot round blue solar pool cover offers a practical way to raise pool temperature, cut water loss, and reduce cleaning time while fitting common above ground pool setups.
