Fish Fanatic
hi i'm not all that new to the hobby (a couple of years now) but i have what i think is a silly question, i have 2 tanks the aqua one ar-620 and the ar-620t and they have filters with the tanks but i wondered which part the carbon is or even if i have carbon. The three parts of the media in the filter are a black mesh type stuff on top, white rings (made of i don't know what, possibly carbon?) and a white mesh, i thought the rings might be carbon but all the carbon i have seen in filters is black so i'm a tad confused, any help would be much appreciated.
