I recently just got an external overflow for my new refugium, man was it noisy. I could barely sleep. If you have these problems look at this website that is below. Also I could not find the 2" to 1" reduction fitting so I went 2" to 1.5" to 1" and still worked no problem, you can get all the stuff from home depot if you are good and diy projects. But I can only say man does it make a difference.
