I have four tanks with canopies that I run without heaters: two RSM250s, and two Evo 13.5s.
The Red Sea tanks have massive issues with overheating, and equipment and lights add an average of 4-5C on top of ambient house temperatures of 20C, with minimal loss of heat at night; the only problem I have is in summer, when my house RSM250 runs up to 29C, even with evaporative cooling (I do not have A/C).
I only have heaters in the IM40 and RSR350, both are in my basement. I think I might ditch the heaters in those, too, if I get Clearview lids (with inserts) for both to minimize thermal loss and increase aeration. I do not have SPS, and existing livestock seem to be fine with seasonal temperature fluctations.
Anyone else running their tanks without heaters?
