In The Swim 12' x 18' Oval Above Ground Winter Cover - Polar Plus - 12 Year - 10 x 10 Scrim - Winch and Cable Included

A swimming pool winter cover is placed over your swimming pool during the winter months to protect it from the elements. Mesh covers are made of a lightweight material that allows water to drain through, but they still prevent debris from entering the pool. This can be a problem if you live in an area with heavy snowfall, as the snow can build up on top of the cover and cause it to collapse. Solid vinyl covers are heavier than mesh covers and do not allow water to drain through. If you live in an area with heavy snowfall, a solid vinyl cover may be the best option. A winter pool cover will help to keep leaves, branches, and other debris out of your pool. This will help to prevent non-living organic contaminant growth and keep your pool water clean and clear. A winter pool cover will help to reduce evaporation from your pool. This will help reduce the amount of pool chemicals needed to keep your water balanced.
