So are the solar pool covers just one BIG sheet of material?? I saw one on the site that was 20x40. My GH is 12x20...would it cover running it with the 40' going down the sides?? My cover will not make it through another winter...in fact it is such a mess that the heaters couldn't keep up with the hard freezes we've already had.. IF I'm gonna have a GH next winter, need to come up with a solution that won't cost me a month's worth of dog food and grocery money
