I'd be interested in hearing from people who use chillers. I am thinking about adding a chiller, but I don't know where to put it. I can't really put it outside the tank; I don't have a tank closet or anything like that to use. And I don't have room in the stand (bad place, anyway). I have been considering actually putting it on top of the canopy. It would allow it to vent heat easily, and on a 175 bowfront, it won't be visible because the canopy is too high.

Any comments? Is that feasible? Are they really noisy?
