When I lowered my water level for closing, the liner floated due to groundwater. This spring I filled the pool and worked out most of the wrinkles, but a few wrinkles remain in the floor of the shallow end. This was mostly due to having to fill the pool with a hose and not being able to be out there 24/7 working the wrinkles out as it filled. I'm trying to find a way to work these out without having to lower the water level significantly, which may open the door to the groundwater floating the liner again. Any advice?
