Was going to set up a fish tank in the basement, more or less it would be a permanent QT. The basement is unfinished, the tank would be off the floor and I would run two heaters in it as well (one in DT & one in sump). My mixing cans and RO water are down there and I have a heater in my SW can and the thermometer reads 78-85 degrees (depending water level of the can, going through the pump and heater makes the water quite warm) Would that be pretty tough to keep warm? Thoughts on this would be greatly appreciated.
