Hi. I have an above ground pool. When we closed our pool, we put one of those inflatable pillows in the center of the pool and then placed the winter pool cover on top of that. I'm not quite sure what the pillow does, but I just noticed that it must have gotten a hole and deflated. I live in cold Chicago. Can anyone tell me what the pillow actually do for your pool in the winter and if I need to do anything?
Thanks!
Thanks!
