Ha, 3 weeks ago I took off my solar cover for the first time in a couple of weeks. There were so many leaves at the bottom that I thought it might take all day to fish them out with the leaf rake as my deck only surrounds about 1/3 of the pool. So I jumped in and gathered them all and vacuumed, with my manual vac. Water was 62! It was pretty uncomfortable (especially diving to the bottom) but I did get used to it eventually.
When I closed last weekend though I managed to do the cleaning all from the deck and a step ladder walking around, I was not going to try it at 58 degrees!
