Do I need Chemical Filtration?

[5x5]

I recently purchased a wet/dry filter that has a mechanical pad filter and bio balls for biological filtration. The LFS never mentioned or set me up with anything for chemical filtration. Do I need some type of carbon pad that would sit in my wet/dry sump?

Note - I have a freshwater tank.

No, you do not need chemical filtration. there are times when chemical filtration such as carbon might be useful, such as removing medication, but it isn't needed on a regular basis.

There is really no need for a chemical filtration such as carbon. The bacteria that will grow on your bio media will do all the work.although people will use carbon every now and then to"polish" up the water. Ie get rid of some of the discoloration and the smell. Just remember that every now and then you have to wash a little bit of you bio media so it will not start producing huge amounts of nitrates
