So this is my second year with our 18x52 intex. The fenced area where we put it barely fit the pool last year and was a little unlevel. This year I extended the fence out another 25' and moved the pool over to where it seemed more level. I used a couple bags of sand to fill obvious low spots. Next I used the 3/4" foam to help with smoothing out the bottom as I hated feeling tiny sticks or roots we missed last year. All looked good till I started filling last night, this morning it is half way full and now see it has about a 3" drop from one side to the next. Is my only good option to drain it try to pull the whole pool/foam base out of the way to try to level it better? If it matters my pool does the strap around the center that the legs slide in so they cant kick out.
