I would just like some helpful hints on the most effective layering of filter media, carbon, ceramic rings, bio-balls, or whatever else you guys think is most effective. This is for my 125 gallon discus tank with a Cascade Canister filter for 150 gallons.
You probably already figured out the most effective way by now, but here is what I been using in my 700.
basket 1 black bio sponge, floss pad, ceramic rings
basket 2 rite size filter pad cut to fit and stuffed in the basket and also another pack of ceramic rings.
