Blue Wave 8-mil Solar Blanket for Oval Above-Ground Pools - Blue

I have a 32 x 16 oval and the matching size fit perfect. After 8 hours of it on, with the sun shining, I pulled the cover back and the top foot of water was like bath water! We stirred it up by swimming and after 24 hours it went up 2 degrees. I think that's pretty good for 25000 gallons of water. It helps to run the filter at night and let it sit during the day. Because it floats and it's light, it isn't too hard to get it on and off by yourself but 2 sets of hands makes quick work of the job. It's a large sheet of plastic so it makes a huge heap so have an idea of where you want to put it while you swim. I personally wouldn't put it in the grass or dirt bc I wouldn't want to put debris in the pool. If you have a deck it will take a large section of it if you don't take the time to fold it up nice. It's worth the money.
