Using a hob filter with bio-wheel. I am assuming that I don't need to use the biowheel since I have liverock. Is this correct? I sure hope so...thing sounds like a waterfall with the biowheel installed.
I've never used one... but a buddy of mine took the wheel off his and he has had no problems. Of course I have read they are bad to begin with but have no personal experience with them causing any problems when left on.
BioWheels are a good addition for fish only tanks where you may need the additional filtration but they are indeed undesireable in a reeftank, nano or otherwise.
