This Bestway® pool cover works well with rectangular family sized paddling pools and above ground pool. A pool cover can be especially useful for large pools which don't have a filter or pump system and are relying on a cover to keep that water clean. By keeping debris at bay the cover for swimming pools can save cash on cleaning, maintenance and changing costly water. The pool protector is made from PE (polyethylene) materials, making it very hardwearing and easy to clean. Elastic band ties enable the debris cover to be fastened to the pool, preventing it from being blown away in windy weather. Drain holes have also been incorporated in the above ground pool cover. The tiny drain holes prevent the pool cover from being weighed down in rainy weather by allowing water to seep through and still stop other debris contaminating the pool water. A pool cover is also great for preventing evaporation of water which can be very important in hot sunny weather. Evaporation can change the chemical ratio of your pool, so the easiest way of stopping these changes is to protect your above ground pool from evaporation, and, at the same time, prevent water loss. Suitable for Bestway® pools. Ideal for a pool sized 305cm x 183cm x 56cm (120" x 72" x 22").
