Under above ground pool goes.
Last year I put up a 15' above-ground pool. I do not have any great level spot in the yard but found an area that worked okay. Unfortunately, it's at the bottom of a slope... so it stays wet easily. This year, I'm wondering what to put under it besides the tarp-thing that came with it. If I made a big area with railroad ties and then filled it with 6-8" of sand, could the pool sit on the sand and be more level? Or would my kids just push on the bottom (which is vinyl) and move the sand around and make more of a lumpy mess? We use this daily and have lots of fun. I'd like to get it set-up a little better but not spend a bunch of money. Any ideas?
