Hi , I just bought a pool yesterday and it's all filed up today ! I thought the ground was pretty level until it was all filled and I notice this morning the shallow end is leaning towards the end that's holding more water. The pool is 18 by 48 inches and is a Coleman power steel pool. My question is this do I have to un drain this pool and find a level area and re fill it again?!? One end measures 37inches and the other end measures 40inches. This pool cost me 400$ and I don't want it ruined but I also don't want to tear it apart if I don't have too !! Let me know my options thanks
