Hi from sunny Southern California. My husband and I, and our gardener, are in the process of preparing and leveling ground for our 16' x 48" 5000 gal. Intex Ultra Frame ABG. I read previous posts about putting the legs on pavers that are sunk level into the ground - and I saw some mention of foam board. How is the foam board used? Since the pool legs will be on top of concrete pavers, a tarp and a gorilla Pad, is there any easy way to put the pavers in the ground prior to bringing out the pool?
