I'm a little confused about cannister filter media options. Can anyone give me a crash course? I have a 38G and a 50G tank, both with Rena XP2s. It comes with the sponges on the bottom, the filter bag with charcoal, and the fine floss for the top.
In the owners manual, there are tons of other options to add. I heard people here say they use the rings. What are the advantages of some of them and what do they do.
P.S. I really like the filter!
