I will not pretend to know the answer you are looking for. With that said if you keep the aquariums above 75 degrees then you effectively have 2 large radiator heaters running at all times competing with the AC. On the flip side, both aquarium heaters have to compete with the room temp created by the AC. Grab a kilawatt and see what you are actually using.

I live in an 1800sq foot home. With AC at 77 and a pool, my electric sits around $425.00 a month during the summer and less than $100 in the winter.
