 I originally had it running on a 70gal DT (30"x24"x24") with about 15 gal in the sump. For lighting at the time I was running 250w MH and 50w of T5. It kept up with that in the summer. The air temperature in the room was somewhat controlled but not great. The system I took it off most recently was less heat load, but I still had it in the system because why not.
