We have had our 21 foot round agp buried except for about 12" on one side 8" on the other for about 2 months now. Everything has been great. We were swimming last night and noticed an indentation about 1 foot from the side of the pool on the bottom. It is about 2 inches across, but when you gently press on it you can't feel the ground, you only feel the give of the liner. So, obviously the dirt is not supporting that small piece of liner. (this is new because we regularly check the bottom of the pool) We don't want to drain the pool to fill it in because we are worried that ground around the pool isn't solid enough yet. Will this pressure from the water put hole in the liner? Any advice on what to do? Thanks!
