Hello! We are putting up a second hand hardsided AquaLeader Creation pool. We have the land leveled down to virgin land and a slope away from pool site for good drainage. We are in central oklahoma so most of the area is on sandstone with rest of it clay. The pool instructions don't say anything about putting pavers under leg supports yet it seems many do with hard sided pools. Is this something we need to add before putting it up or is it not necessary for every pool? Thanks!
