I have a 16x48 Intex ultra frame pool that I put up this summer. We leveled the ground prior to setting up by using a sod cutter and then digging out the high side. Well for some reason we didn't do a good job and now there is a 2-3 inch difference, it seems the ground settled some because it seems to be getting worse as the days go by. There is one area of the pool that almost looks like its tilting slightly. I'm worried about safety so we are going to drain and re-level the area again. I know it's kind of late in the season but my kids love the pool. it's about 6000 gallons of water and I'm not sure how I go about draining it without flooding my yard completely. Also we got a terrible case of algae even after consulting the pool place locally. We just shocked the water so I'm not sure how that will effect the grass. Any advice would be greatly appreciated.
