Yup, the room is separate from the house. I will eventually run a gas line to the room and get a wall heater unit, but I've put myself on a spending freeze for the time being. According to a utility company representative, heating via gas would be 1/4 the cost of using electricity. I considered using electric space heaters in the meantime, but the models I have looked at draw upwards of 1,500W, so I might as well just heat the water directly at that wattage. I've heard conflicting information on this, but I tend to think that using 1,500 watts to heat the water directly would be more efficient than using 1,500W to heat the air enough to get to my desired water temps.
The good news is that the room is well insulated and the tank does not appear to lose very much heat overnight...
I conducted a little experiment: Last night I left all 3 windows open to see how much the water temps would drop. I was surprised to see that the room temp stayed at 70F (even though outside air temps fell down to a low of 58F). I believe that having such a huge body of water at 85F kept the room at 70 (even with all the windows wide open). In any case, the good news is that the water temps fell by only 2.8 degrees, from 85.5F to 82.7F. Tonight I will keep all windows closed and see how much heat loss I find in the morning.
lol- Virgin acrylic is a beatiful thing.
Thanks!
I've never attempted a cichlid community. I've only ever done one or two cichlids with a bunch of dithers. My fear would be having to try to net out some poor little guy that was getting his butt whooped by some of the brutes you mention, but I like that stock list.
