Bought a used pool on cl. It was listed as 18x33. Purchased liner. Got pool home and now all installed. We really wrestled with the overlap liner and looking at the paperwork on the pool and instructions it says 18x34! I have it filling right now but I am freakin out! It is mostly sunny and 80. Hoping the ends will stretch, but it seems like the water is just traveling up without really pushing it down. Lioks like my bottom seam will be short on each end. Sides are fine. I thought maybe it wouldnt matter so much since people dish these out. Help!
