I am having a problem with internal metallic vibrations on my Rena 400. This is my 3rd one (I returned the first 2). I've tried new tubing, new/different airstones, different flow settings, etc. and I am at my wit's end. The noise is driving me insane, especially since my 55 gallon is right next to my bed!
Each pump has run well for 3-4 days, then it starts the metallic vibration inside the housing which fades in and out from time to time and gets fairly loud. The problem goes away when the pump is run without any tubing attached, which leads me to believe it is some sort of backpressure issue.
PLEASE HELP! THANKS!
