If you have an Axolotl and are having trouble lowering the temperature in your aquarium, this is the solution. I was a little dubious based on the reviews but this fan lowers my tank temp by 10 degrees, my frozen water bottles wouldn't lower it even one degree so this fan works wonders. The side of the bracket doesn't fit the lip of my tank, but if you bend it 90 degrees you can easily place it on the side of your tank. Also, you want the side blowing air to be the side facing the water.
