I'd just like to chime in here - Joe is absolutely correct.
Evaporative cooling is very effective. I have a reef tank, and
there temperature is much more of a concern, the lights generally
much more intense and therefore hot. If the temp fluctuates by
more than 5-7 degrees F above normal corals can bleach and die.
I have 2 4" computer fans in my hood, and when they are on they
can keep the tank temperatures 2-4 degrees cooler than the ambient
room temperature. More fans, more cooling. If you have a sump
you could put a really big fan on the water in there.
You will have to top off for loss due to evap (I loose about 1
gallon/day), but you can automate that with a pump and a float
switch, especially if you have room underneath your tank to store
the equipment. Also it can be useful for dosing fertilizers and
