The purpose of biofiltration is to convert ammonia to nitrate. In a 
planted tank the plants consume the ammonia. Carbon removes dissolved 
organics, but it removes a lot of things plants use too. The only thing 
left is mechanical filtration which isn't usually needed unless 
something is going wrong.
