I have a 15 mil solar cover, a little pain in the you know what, but Between the solar cover and the solar collector my pool stayed at 78 this morning and was up to 85 by 3pm. I also had to vac today for 1-2 hrs because of Algae.
So I missed two hours of good sun. The air in Mass. today was dry and warm so it felt good when you got out and put a towel on and then felt even warmer when I got back in. One word: GREAT! I had some friend over and really injoyed it...
