Hello, I hope you can help a new pool owner putting the pool up himself. I have a 21'x52" pool and my ground is level within 1" all around. The sand is also level within an inch and compacted with a plate compactor. My problem is the sides of the pool. 80% of the sides are vertically square and the others ( almost 180 deg off) are 1-2" off square. Ether the bottom needs to come out or the top needs to go in. The rails don't apear to be scaloped on top or bottom, but if I try and square them I get buckles in tplease help!he sidewalls. I have about a foot of water in the pool now and not sure what to do.
