I am setting up a 20g tanks with a Fluval 204. It comes with media but when the time comes, can I use whatever I want in it? I have loads of filter floss and ammo-carb in the house and wonder if I can use the floss and ammo carb instead of the carbon that came with the filter? Any Fluval owners out there? What do you use? How often do you change it?
