I run my AC all day evry day all summer long my tank today is at 80.3 with the MH & T5 on since 10am . my electric bill is around $150-$180 a month not to bad
Me too. I try to keep the AC on as much as possible. I'm somewhat lucky in that I can block off the living room and kitchen area so that the room AC unit only has to work in that part of the apartment.
Right now I'm setting up a new tank but will have a decent sized fan running over the sump along with smaller fans strategically placed in the canopy.
My Metal Halide will be about 14 inches off the surface of the water as well.
