First, I want to say I love the site, and have recieved really great information and advice so far.
So here's my problem. I set my 15' x 42" metal frame pool up in my backyard, which I thought was level and relatively clean of debris. After setting it up, I've noticed rocks under the bottom of the pool, which have caused minor leaks that I've fixed with the underwater patches. However, since the water was leaking, it softened the ground around the support legs, causing them to sink and make the pool really unlevel. I am draining the pool now, and want to prep the site better for it. I've seen confusing information on the use of sand, and don't think I can afford to buy expensive pads or build a permanent concrete pad for a temporary pool. I am looking into how much it will cost to by enough sand for a 16'x16'x2" base. If I were to place that sand beneath the pool, would it not just be smashed outward when the pool was filled? I am just not real sure what to do, and wish I had thought a little more about it before I set it up.
