I realize this question is early for the season, but any good ideas regarding which is a good solar cover to use? Is a solid cover better than the multiple discs? A solar blanket is the only heat source that I currently had (the last cover filled the pool up with the small plastic circle as the cover was falling apart). Sorry if this has been discussed somewhere else in the forums. I am new to the site and am still figuring everything out. Thanks for the help.
