Ok, right now my 55g has a Whisper 60 on it. I probably need more filtration on it and was going to throw on another one, everyone says dont' use carbon so I'm gunna remove that but what can i add for more bio filtration?

I saw on here in someones post that they used the teflon pot scrubbers for more bio-filtration because they have much more surface area. I bought some and am trying them in a cpl of my tanks now with no problems. I found them in the local dollar store 3 in a pack for $1.00.
