I am a new pool owner, well sort of. I now live with my brother and am now attempting to get this pool up and running. It has been unattended for the last 4 years (since his wife passed). I have drained and cleaned ande have started to refill. Problem is there are wrinkles in bottom along wall and particularly in deep end area. On the low end, the liner is pullled a little away from wall and is very tight. It now has about 6 to 8 inches of water on low end. Help! I dont know what to do.
