I am currently filling the pool..its a 22' x 52" intex. My question is can I put one of those hard plastic plate like things used for moving furniture under the legs? I have pavers, but thats a lot of digging and not sure it would work any better than the discs I'm thinking of trying. They are thin so wouldn't have to dig, and I have a very large tarp the pool is currently sitting on. I have compacted the sand underneath with a machine and watered it a few times..but one half is almost 8 inches of sand and i'm worried it will sink without something under the legs...also, how do I get the small creases out of the bottom of the pool? NEED answers FAST, thanks so much!
