I would only use carbon when needed. There are debates either way, but I think that it is unessary to run all the time. Carbon will remove iodine and other trace elements from the tank. It is good to run occationally, IMO, to remove cloudiness and discolloration from the water from what your protein skimmer does not remove. Just be sure to use a high quality carbon that is not going to leach phosphates into your tank.
