When we opened our pool this spring after the winter season we had a tremendous amount of leaves and rain water on the top of the cover. This year I have been thinking about getting something to float in the center of the pool to "raise" the cover up and stop it from "sagging" into the middle of the pool and holding all that water and other stuff. We had a siphon thing hooked up but it didnt work to well... I had thought about getting a couple of large inner tubes and setting them in the middle and them putting the cover over them but not sure if this will work or not. Can anyone give me some ideas or tell me what they do to close an AG vinyl pool for the chilly months. Typically we drain the water lever below the return line and drain the filter and of course do the winter chem thing too ...
