We have a metal-framed Intex 18' x 4' pool. Last year, the water was pretty cold. This year I'm thinking about getting a solar cover. I was going to get those "solar fish", but from this forum I learned they don't work too well.

Is the Intex solar cover decent? I don't want to spend a fortune and it's only $39.00 in Walmart.

Also, will the solar cover really help the water and when should I put the cover on? Leave it on all day & night when not swimming, or just use it at night?

Any advice is appreciated. Thanks!
