I just set up and filled my 18x48 easy set inflatable ring pool. I thought I had the ground level but after filling it, It is leaning to one corner a few inches. What should I do? I was thinking about carefully digging out under the higher corner to relieve some pressure. Or draining some water and try to wedge a few sand bags under the lower corner. I really dont want to drain the whole pool, already have the salt/ph etc good. Is it in danger of collapsing? Like I said it's roughly 2 inches or so off to one corner and can see it leaning. Any advice?
