is activated carbon and zeolite filter beneficial in the aquarium?

It is beneficial because it can remove chemical filtration a lot of toxins in the water. Zeolite removes ammonia (which is not needed after your tank is cycled, because the beneficial bacteria that are making this for you) and removes dissolved organic carbon compounds. The thing about carbon is that it only lasts about two weeks if carbon is good quality, and then there to change to avoid downloading these nasty substances back into the water. Many fans of carbon to be a pain in the ass and you do not use it for those reasons, but I think that carbon and other absorbent media Purigen can still be used and be beneficial if they change frequently.
