Review on Black Zoo Med Aqua Cool Aquarium Cooling Fan: Enhancing Efficient Temperature Control by Nicole Houston

I used it to cool my axolotl tank from 70 degrees to 66 degrees! I have a 29 gallon tank with an all black cap, so most of the fans recommended for the Axi don't work for me. I have a naughty cat so I need a fan that works with a sturdy cover. The fan outlet is small and only goes through a gap at the top where the filter fits. It doesn't generate super strong currents (the power is adjustable so you can gently blow on the water surface) and for the price a temperature drop of 4 degrees is great! Very happy. Ideal for axolotls.
