I have a 15x30 above ground doughboy. We just found out it has a hole in the liner. We drained the pool, repaired the hole, replaced the sand that washed away, and started to refill..............but wait. We realized that the bottom of the pool has lots of wrinkles. Will these correct themselves? There is now about 6 inches of water in the pool, can we solve this problem with the water in the pool? Any help is welcome
