How long is this good for? An hour, 2 hours?
What about those blue coolant paks or whatever they are called that are used in coolers? Would they last longer?

Hey Patrick, and others, here is a great cooling trick I learned last summer during the heat wave when I didn't have any canopy fans.
Take two empty 2L pop bottles, remove the labels and fill them with water until they are almost full (leave some room). Cap them and put them in your freezer overnight to make a big 2L popsicle. Now when you have high tank temps just float one of the frozen bottles in the tank to help lower the temp. :cool:
With this method you are not melting fresh water in the tank. Also, by having two bottles, you can rotate them, one floating, one freezing. [img]smile.gif[/img]
