In a cool ground floor suite, my unheatered reef tanks stay around 78F normally in the summer, but during the heat wave it was around 82-83F with fans going. That's not bad considering the max. room temp hit 83-84F on Saturday, which was still a lot cooler than outside. Sunday, I was able to leave my MH lights on their regular timer schedule & only shut off for a few afternoon hours on Sat. & Friday.
