18ft solar cover on a 20ft pool

[Havlc2u]

Hello Currently I am not using a cover on my 20ft ultra frame pool but I have a
18ft solar cover from a old pool would you guys think it would help to trap some heat the pool went from 78 degrees to 74 degrees pretty fast like over night one night. I am trying to not have to buy one.

That would definitely help. Wouldn't be as insulated as a full cover obviously, but the only heat loss would be around the edges. Definitely can't hurt.

Absolutely it will help. But obviously if the full 20 feet were covered it would be more effective. Check the classifieds in your area for a small blanket. Might be able to get the extra 2 feet for little or nothing.

Ya people in my area don't have to many pools. I am in Fargo ND most people don't think summer is long enough
