Just put in a pool last summer in South Eastern Texas. I want to get back in the water and was wondering what a solar cover would do for me. Warehouse Pools have a 12 mil cover I'd have to trim to size for about 160 bucks. Have any of you used this brand? It is advertised to warm the water 10-15 degrees, does this sound about right? I know it depends on the sun intensity ect... Just looking for some feed back, Thanks in advance.
