Above Ground Solar Swimming Pool Covers
Do You Really Need One????
There are solar pool covers that you can potentially use for an above ground pool, but above ground pools generally do not need them. If you want one, though, there's good news! They're pretty cheap and will probably work even better with an above ground pool than with an in-ground one.
The purpose of a solar cover is to trap the heat from the sunlight in the water during the day, and to keep it there over night. With careful use, it can help heat up the water temperature quicker than would otherwise happen.
Above ground pools though don't have as much water as an in ground, and they tend to heat up quicker and stay warmer than in ground pools do (which can actually be unpleasant if the water starts staying too warm).
