Does anyone around here use a chiller?

[bprice]

I know this is a strange question to ask when the temperature is about 10 degrees outside right now, but I am thinking about this summer. Most of the tanks that I have seen are in the basement or a central living area, so does everyone just keep them cool with AC? My tank is in the wall between the living room and an add-on sunroom and the temperature fluctuations are much greater than in most of the rest of the house. Any suggestions? I just connected a 120 gal to my 125 gal with about a 50 gal sump.
Thanks,
Bruce
