I need to level the ground for our new pool. It is an Intex 16' x 48" above ground with metal frame. Our instructions say only put on firm ground and don't use sand. However I am having a heck of a time getting the ground level. We have clay soil. Are there any tricks to doing this, or inexpensive tools to help me. I'm so frustrated if it weren't for the kids I would have given up. :(
