Most on here will say not to use carbon. Most will recommend Purigen and so will I.
What brand canister filter is it you are setting up? If it were me I would pick up some Seachem Matrix or Eheim Subtrato pro for biological. Leave room for a bag of Seachem Purigen. Use the rest of the baskets for mechanical filtration. The ceramic rings are fine if they are a good quality. Some of the ceramic rings I have ran across are not very porous.
Is this buy chance a Sun Sun?.
