I don't usually close my pool. I keep my water level up to the skimmers and once it gets cold the freeze protection turns on my pump at a certain temperature. As soon as it starts warming up, I adjust chemicals. It doesn't get a funky color or anything so I enjoy looking at it, even when I can't swim. I usually have a season when the leaves are falling and I have to clean out my skimmers every day and clean them out of the bottom. But, last year it was more than a season. It seemed like it was all year!! So, I was thinking about getting a mesh cover and covering it using water bags just to keep the leaves out. I would still keep the water at a certain level and run the pump, etc. Does anyone have experience with this? All of the forums seem to be talking actually closing the pool. I wouldn't actually be closing it. Also, do you just put it over your steps and diving board, etc. How much length would you allow for that, if you did?
