Cooling a tank?

It's looking like a hot summer this year, and my room doesn't have much in terms of air conditioning. While cycling my tank, the water managed to be in the low 80's almost constantly, even though I kept the lights off! Does anyone know any (preferably inexpensive) equipment that I can get that will cool the water down?

My favorite cheap way is to get a few ziplock sandwich bags fill the bottom 1/4th with water and freeze. Then when you want to lower the temp of the tank just stick in a bag into the filter box unit and allow to float until it melts and replace if needed.

I've read about people filling a coke bottle with water then freezing it and floating it in the tank to cool it down. A bottle would probably stay frozen longer than a ziplock bag. You could freeze a few bottles and just add one while another one is freezing for the next day.

Just had another thought, you could buy some of those freezer bags that have the blue gel/liquid in them. I'm sure they're suppose to stay frozen longer than frozen water.

A fan blowing across the surface so it ripples a bit will help also.

I have fans across both my reef tanks but they have open tops. How about a room air conditioner?

So after 4 summers of living in this sauna of a room, my mom decides to mention that we have an AC unit in the attic I can use. :dunce:

fans are good, my thank is sealed at 1.022 and i use a small HP computer fan, it colds the water from 29ºC to 25º C all the day long, a little but noisy but efective.
