I have been reading a lot of posts recently about activated carbon being a waste of money, and with my cartridges clogged up, I am thinkinking what to put in my emperor 400.
I have bought 14oz of aquarium cotton, and is just contemplating on what else to add if carbon is an unnecessary choice. My tank does not smell and does not have any unwanted colors.
Thanks in advance!
Also the emperor 400 have two empty boxes for extra media, what would be good to place in there?
