I have a solid cover and use a pump in the center to remove rain water. It works but accumulates leaves and looks a bit unsightly. I’m considering tying an inner tube in the middle of the pool so it will hold the center of the cover higher than the sides and let the water drain naturally. The only possible downside I can think of is that it may cause problems if we have high winds that get under the cover. Has anyone else tried this method and does it work?
