Keep your pool clean, pristine, and heated when it's not in use with the Bestway round solar pool cover. The specially designed solar pool cover creates a greenhouse effect in your pool. By floating directly on top of the water, the cover traps heat from the sun to keep the water warm and the debris out. Above ground pool covers are a must-have accessory, preventing algae growth and reducing the amount of chemicals you need to use to keep your water in tip-top shape. This cover is perfect for a Bestway 3.05 m (10 ft.) round frame pool, round steel wall pool, and round inflatable ring pool.
