As long as we are on the pool topic, how does everyone warm their pool? Solar cover? No cover and direct sun?. My pool has no shade cover until about 6pm it starts to move into shade. Still my pool never really gets that warm, 83 tops. I tried no cover lately during a hot spell, and it seemed to do better than with the cover. Maybe the sun shining all the way through the water? My wife insists on running the filter on sunny days with the cover on and I think that defeats the solar cover purpose
