Carbon bed is a new one on me. I'll look into it.

I'd look at the "sand bed in a bucket" thread that links to the reefcentral thread on Calfo's forum (I think) where he dicusses using a really deep sand bed, like basically a big box filled with sand, as a detrification device. You don't put animals in it or any light on it or maintain the bio-diversity like a true DSB. You just let the bacteria colonize and apparently it really helps with nitrates.
