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

The supplied fan is too weak to significantly affect the temperature in the aquarium. Or maybe the design of the blower loses too much resistance. When it is on and you put your hand on the exhaust nozzle, you can hardly feel a small flow of air. Also, it's a bit noisy. If they would just spend a few bucks more and get a better quality, quieter fan with better performance, this would be a good product. Maybe I'll wrap it up with a better fan. Good idea, bad execution. In that respect I would not recommend it.
