Ok so we got all the styrofoam laid tonight. Did not get the liner in because I remembered it should not sit without water in it. So we're hoping to get the liner in tomorrow night and hopefully have water delivered on Wednesday. I'm too chicken to use my well. I decided against wall foam because I didn't want to wash down the interior walls (used pool and walls are a bit dirty) and I knew the foam wouldn't stick. So I skipped it. Also, didn't use a cove because the styrofoam covers the wall channel and any rough edges. Is this ok? As long as I use duct tape along the edges to join the styrofoam with the walls? We ended up putting a thin layer of sand down, then 1.5" high grade styrofoam. Am hoping my beaded liner will fit like a glove tomorrow night. Stay tuned............
