77-82 degrees is what mine runs at. Heat is a 350 watt in sump heater. For summer my hood has 2 fans with regulators for speed.

only suggestion......watch temp in summer......too high.....equals fish stew. I left for a week about 4 summers ago.....let friend house sit.....thought he'd save us money by not turning on the central air. Yup you guest it...like 98-100 degrees for 5 days. ALL inverts and corals took a beating.
