Keep your pool clean and spotless when not in use with the Bestway Round Pool Cover. Covers for above-ground pools are an essential accessory; they prevent dirt, leaves, and debris from entering the water, inhibit algae growth, and reduce the amount of chemicals needed to keep your water in pristine condition. This pool accessory features drainage holes to prevent water accumulation and stretching from weight. A rope is integrated into the cover's lining and can be tightened to keep the cover in place, even in windy conditions. This cover is the perfect accessory for a Bestway 3.96 m round frame pool, a round inflatable ring pool, and a 3.66 m round steel wall pool.
