I'm having the same problem. I jabber a 24x15 Esther Williams oval aluminium pool. We put more sand in bottom. Put liner in. Liner didn't fit.took it off.dug out sand. Put liner in ,still didn't fit. Raised one side of pool up that was sinking bc is 40 years old. Raised it 2 inches, tried liner again still had wrinkles. I'm tempted to pull out back and take more sand out of the bottom?
