If it makes you feel any better it happened to me too. I got home on Friday to a 87 degree water in my tank. I turned th A/C on full blast opened my Sump's door and put a couple of Fans blowing on the water. I lost my Skunk + Fire shrimp and 2 emerald crabs. Thank God nothing else. I would have been really pissed if my BTA died and ruinned the water! I'm seriously considering buying a chiller but I want to try a cheaper solution first. For those of you who use fans how well does it work in keeping the Temp down? I was considering getting a couple of these on Ebay. I wonder if they would do the job. http://cgi.ebay.com/Metal-Halide-Aquarium-Chiller-Cooling-Fan-4-fan_W0QQitemZ230134970490QQihZ013QQcategoryZ46314QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
