I know we're a bit away from pool closing time, but I've been struggling with this since we bought our house 4 years ago. We inherited an Esther Williams pool with our house, with a "walkway" all the way around it. It has made closing it for the Winter (we're in Western NY) a challenge. I've gone through a couple of covers that were completely ripped apart by the wind. I've tried water bags, strapping the covers down, etc. Nothing seems to work. Right now, I'm using a mesh cover. That works decently, but I end up with tons of algae. It took 2 to 3 weeks of the SLAM process and running the filter 24/7 to clear it this year (it was killed quickly, but filtering out the dead took time). Is there anyone else out there that has a similar pool? What are you doing for the Winter?
