an anyone give me advice? We are putting in a new liner, It is a j hook liner. Any way we finagled it, it put wrinkles at the wall but mostly wrinkle free on bottom. My main concern is one of the long sides (21x42 above ground pool) has excess liner at bottom, but the opposite side seems very tight (it is pulled away from wall approximately 6 inches.) I am worried it may cause damage to he pool wall? It currently has about a doot of water in it as we are filling it. Drainimgnis an option if this seems like it is a provlem. Today was not sunny, so no heat to help stretch it. Do we need to be worried about this?
