Filter Media in UGF
Hey everybody, I have a question. After looking at my UGF for awhile I really wanna use it and had the thought: can I use filter media (specifically ceramic rings) in the lift tube of an UGF to really push my amount of bacteria in the tank. Could I also put carbon in a bag in the lift tubes? I was thinking ceramic rings would be better because I wouldn't have to replace them really at all.
