I often sleep with a fan in my room, so at least i won't be losing any sleep. It would annoy me if it was in the living room.I honestly don’t mind the noise. Yeah you can hear them but my overflow is loud as heck to begin with because of the way I did it. But agree..about as loud as a box fan
When are you getting that thing wet?!I have Reefbreeder Photons on 3 tanks here and you have to be standing right next to them to hear the fan when it kicks on. The new tank has Radions. I'll see how I like those once the tank is filled up and running.
