haha, odd! if it's a screw up and you're supposed to have the needlewheel do you want to help a brother out if they send you a new one? I'd be happy to offer you a few bucks for it.Dejavu, I got skimmer with or2500 with regular impeller no needle wheel.
I'm debating turning my frag tank into a cryptic fuge like yours. My few zoanthid frags down there just don't justify a stand along frag tank. What do you think about yours? Do you think it's a potential nitrate factory or do the little critters in there help out? I've got some reading to do, but any guidance you could offer would be of great help as well.
