Just an idea.. but wouldn't it be better to get an AC that will keep the room and the tank cool?

With no one home, AC on, fan on sump, top proped open, My tank still hit 84.9.
 Since I am going on vacation for 9 days, i can't risk it. Finally broke down and bought a chiller. It will get to run for a week before I leave so hopefully i can iron out any potential problems, appears to be working good so far though.

Currently 29.9C with one MH light on. So I have just turned off all lights now. Room temperature is 30.5C using the same thermometer. I guess the evaporative cooling on my tank is making it cooler than room temperature by a bit.

I think the easiest solution for tanks without chillers and what not... just cut back your photoperiod. Turn the lights on in the AM , and off once it hits noon.. keep 'em off til later in the evening.. turn 'em back on again if need be. That's what I am doing.... 20g with 250w HQI in a bedroom and I am at 83-84... not too bad considering.

Except for the fact that it is barely getting under 20C at night here. I wake up in the morning and the tank is still 83F, because the house doesnt even have a chance to cool down. How do you cool down a tank colder then the air?
Global warming i tell you...  Gotta get central A/C by for next summer!

http://www.aquarticles.com/articles/...SettingUp.html "Through the proper use of fans (evaporative cooling), you can usually drop a tank's temperature by a good 5 degrees. Fans are great! " http://www.coralplantations.com/pages/heatissues.htm "The effect of evaporative cooling is greater than most people realize. A small desk fan mounted above a tank blowing across the water can drop the temperature by 3 degrees or so depending on the tank volume. " http://www.vividaquariums.com/troubleshooting.asp It is possible to cool an aquarium by 5 or 6 degrees using this method of ventilation and evaporative cooling.
