You don't have to take anything out of the filter unless it's some sort of ammonia remover. Carbon new or old will not hurt your cycle. Do you have any bio-media in your filter?(Bio-media are Bio-balls, or ceramic rings that benificial bacteria attaches itself to). Without bio-media in your filter the only thing that will hold good bacteria is your gravel,decorations,rocks etc.
