Hello! First time posting! We just installed a 21ft Doughboy. The area was leveled to within 1/2", measuring with a laser level. All leveling was done by digging down. We planned on hooking everything up, pump and filter, but it got too late so the pool is only filled halfway right now. The problem is that one of the floor plates is not touching the ground at all. We have no idea what caused this. It can't be that the floor plate moved when installing the wall because the ends wouldn't have met up. It's just raised in the air about an inch maybe less. Any ideas? All other floor plates are on the ground.
