Hello all, I have a penguin 100 bio wheel and I am totally ready to give up on it. Its SO loud, or just making odd noises for no apparent reason. I check inside frequently and the space where the propeller is housed is always clear so I have no idea what's wrong with it. Any of you guys know any fairly cheap quiet HOB filter that I can replace it with? Appreciate any advise.
