Got pool up. All seems good. Got a J-Hook liner installed top rails on. Got all wrinkles out of floor. Got about 6” of water in so far. Bottom seam isn’t touching cove. Liner seems very tight, liner isn’t touching wall either. Seems to be evenly pulling away fro wall all the way around. It was 60 and sunny when I installed it. Suppose to be about same weather today so I’ll wait til warms up mid day to fill more. Everything I have read says liner will stretch but seems it need to stretch an excessive amount. Does this seem right and I’m stressed for nothing?
