I guess I need a solar cover.... Thanks to this forum, I've successfully upgraded all of my equipment and added solar panels a few month ago. The entire family has loved the 86 - 88+ degree water all summer long. Now, even with temps in the high 90s, I'm loosing a ton of heat each night and I barely recover each day. We're still getting up to 84 or 85 by the end of the day, but I'd really like to extend the adult season a little longer.... Any recommendations on what I should get? 12 mil vs 14mil, etc... Anything on Amazon worth buying as we get free 2 day shipping with prime. A 20' X 40" has plenty of room to cut to fit. Should I keep it one piece or two with the limited space to roll. Any advice from the group???? This is what I have to work with:
