I have a 27ft round AGP. We installed the liner and have about 8 inches of water in it. We have only about an inch and half of overhang on one side but it seems to be staying there and not slipping. My question is...if does begin to slip as we fill it, can I take off the stabilizer bars and coping in that area and pull it over more without worrying about the walls collapsing or other major issues?
