My husband and I recently bought the Bestway 22ftx52" PowerSteel Frame above ground pool. We spent two days leveling our ground using a peg in the centerpoint of the pool, drove into the ground with a 12' long 2x4 attached to it at a swivel point with a level taped to it. We used this to level all the way around the circumference of the pool, adding and taking away dirt as needed so that it was within one inch of level all the way around. We then added 2 tons of sand and graded it out to be as level as we possibly could. We set up our pool last night and started to fill it. I have only owned a pool once and it was several years ago, so I don't remember much. My husband is worried that the ground is too soft because you can still move the sand around (with only one inch of water, not even all the way across the floor) and I said I think that's not a big deal. The weight of the water once the pool is filled will compact that sand down further right?? Also we were frustrated because the once perfectly level surface now has dips where we are pushing out the liner to the edges. Personally I think you will never be able to get it COMPLETELY level on the floor and there will always be small dips. Sorry for the long post but we are going to continue to fill it today and are just worried if we need to take it down and start over. (I sure hope not!) Thanks for reading! 
Good luck on your project.
