Active Carbon is usefull in helping cleanse ammonia, chlorine, and clarity of the tank. They're considered as bio media which you add to your filters or substrate. DONT add it inside to the tank, after awhile carbon looses its purpose and will have to be replaced again, so you dont really want hundreds of carbon particles mixed in with your gravel/sand.
