My Apex controller has a seasonal table for temperatures... In summer the temperature is controlled to 27.6 C and winter it's controlled to 24.6 C. Saves heating and cooling energy. I don't use a cooler, but fans and they work pretty well. If it gets to hot in the summer the controller shuts off the metal halide lights. Any given day the temperature swings by 0.3 C.
Funny, being a SCUBA diver, I find that there's all sorts of thermoclines and currents in the water that lead to big and sudden temperature changes. I don't think regulation of temperature is a big factor, but keeping it within limits is.
