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] |
