Hey guys, i picked up a 125 gallon that has 2 magnum 350 canister filters on it. I cleaned one out today and put a new pad in it, i saw the person before me had just filled the inside compartment with carbon. I ended up putting a few scrup pads in there, and then putting some carbon in a media bag and putting that on top. Now its making noises and it sounds like its coming from the motor area, like the spinning part. It doesnt make one steady noise but it does constantly make noise. Anyone have any ideas to why it started makeing noise and how i can try and fix this please?
