Above ground pool covers are a must for every above ground pool owner. If you get them on before the big storms, clean up after will be much quicker. Pool covers are also the best way to winterize your pool.
Winter pool covers are made for just about any size above ground pool. If you cannot find an exact match just go one size larger. A little extra cover will not hurt nearly as bad as not enough.
Above ground pool covers protect the pools from the environment and they also protect little kids from the pools. A good quality pool cover is one that you can actually walk on without damaging it. It should easily support a child and allow them to get off the pool safely. Most covers have a wench and cable system that get cranked up tight around the outside of the pool. Many cranks have a padlock included for added safety.
Winter pool covers are the best way to winterize a pool and they are the best protection from the summer storms. It is also nice to have a solar blanket on hand to put on in the early spring to get the water warmed up and ready for swimming weeks ahead of pools without one. In colder climates solar pool covers are used all summer long just to keep the pool warm enough for regular use.
Make sure also that you have all the necessary pool cover accessories. You will probably want things like the pillows for under the cover, the pump for draining the water off the top and guards and plugs for the skimmer. Another useful item is the Winter Pill to be used before covering the pool for the winter season.
