I just purchased this pool. I live on a lagoon so the land naturally is sloped and we have rocks. We rent the house so we can not dispose of the rock. I have set up the pool on plywood to have a flat bottom, leved out the rocks then filled it. Only when it was full did I realize it was way off!!! What is the best way to level it on rocks and is there a way to lift it without emptying the pool all the way. I have already started to empty the pool. It has about 6-8" left to be totally empty. Thanks for the help in advance!!!
