The ecosphere is stagnant, so I'd remove that. My name remains there forever.......*groan*.
I believe that cp growers and FW hobbyists have a lot to share with each other. We use many of the same things(for different reasons...like peat to make blackwater or to enrich the substrate rather than as substrate). The cp growers might also try doing a growchamber "planted tank" style.
I'd vote on leaving it. however if you remove it, its not like its the only forum available on FW fish(far from it).
Edit: To late, but at least you did as I suggested!
