yeah carbon will help or maybe gravel vac. ever considered a protien skimmer?
I agree ^^
Carbon helps, but those who aren't aquarists will be more sensitive to the organic 'earthy' smell that a healthy fish tank has.
I imagine the only way you don't get that smell is if you have a 24hr drip system? I'm not sure on that though.
