Me too, but I couldn't wait. I pulled the cover off this past weekend. Water looked good. A toasty 54 degrees. Some worms and a few leaves and 'leaf-dust' in the bottom, but other than that, pretty clear. PH was suprisingly close to 7.4, but I want to bring it up a bit before I start to chlorinate. Every year at this time I contemplate getting a heat pump......
