Question - I have a MaxiJet 1200 Powerhead in my tank to create some
current for my fish. I have it unplugged though because it is rather
noisy - it makes an almost grinding noise; I think its the impeller or
something, and I'm not sure how to fix/clean it? Anyone have any
suggestions?

Here is a section in the document about clearing your power head:
