My husband and I installed this above ground pool last summer. We leveled out the ground and put sand down under the entire oval structure but did not do a great job filling sand under the four leg braces on either side. A year later the braces are bending into the ground and the walls are bowing out. Is this thing going to collapse or are we good? It’s hard to imagine that the legs can sink any farther than they already have. Any thoughts? Do we need to fix it? Is it fixable? There is 1-2 inch difference in space from the water to the top of the pool in different places.
