We swim yesterday for the first time this year. The water was 78 degrees and the pool enclosure mellowed out at 107. It was great. We don't have a pool heater. Just the enclosure and we also purchased a solar blanket that helped increase the water temperature a little. First swim April 5 2009, not bad for NC and no heater. Thanks for all your help with ordering and installation.
