I am preparing ground for 15’ intex metal frame pool, which is not the type one can bury. The first thing I read was to dig down to firm ground, which I did. And herein lies the problem: with attaining firm, level ground, and taking into account the slope of my lawn, the west side of the pool will be a foot in the ground (see pic). The east side is fine. I want to put a pool in this location. Should I return Intex pool and buy one that can be semi buried?
