Do I need activated carbon in my aquarium filter? & what are the benefits of chemical filter media?

Activated carbon is non-reusable & needs to be disposed of after use, therefore, aquarists prefer saving it for specific periods when they have dissolved organic compounds or tannins that they want to get rid of. If somebody wants to take photos of their aquarium, then they might decide to use activated carbon to make sure that water is crystal clear. Nevertheless, most aquarists do not prefer using activated carbon every day as their performance is reduced very quickly when they are saturated with impurities. Hence, they can work for temporary periods, & then need to be replaced with fresh carbon.

Is chemical filter media necessary?

Chemical filtration is not necessary unless you have tannins, medications, & odour in your aquarium water. Usually aquarists do not prefer chemical filtration because they work for limited instances. In order to check whether your chemical filter media is working, it is recommended to check if it is still getting rid of the dissolved organic compounds. If chemical filter media is no longer removing the tannins or dissolved organic compounds, then it means that your chemical media needs to be disposed of.
