I changed the impeller recently, and after listening to a broken impeller for a few weeks, I can't seem to remember how my filter is supposed to sound. Its like a low humming/vibrating noise, and at around 15ish feet away, the sound of the water overpowers the noise. Is this noise common on hobs or do I need to look for something else. (It could also be the impeller breaking in, but I'm not sure)
