We moved into a house with a pool in November. I have a solar cover with a reel to take the cover off when using the pool. I was reading the literature that came with the solar cover, and it says to cover the solar blanket with the white polyethylene cover that came with the solar cover to prevent the sun from damaging it while it's rolled up. This white cover is so thin that it's starting to shred and won't be able to cover the roll too much longer. I checked at Lowe's and Home Depot, but the only have clear and black In the paint drop cloth section. I also did an online search and nothing really came up. Does anybody know where to get a large sheet of white polyethylene? Does anyone not cover their solar cover when rolled up?
