I just got the Rena XP3 filstar filter for christmas today, i'm so excited! It's for a 55gallon tank, that's already setup and been going for a while.

However I have a question and that is....what all do you who have canisters (of any type) put in them?

I know you need something in there to hold bacteria and the filter; The filter came with a 30 PPI foam pads and two 20 PPI foam pads. It also came with I think 1 or 2 micro-filtration pads. Oh and it also came with 1 pouch of Rena Filstar Phos-Zorb.

Now rena offers the their super activated carbon pouch, water softner pillow, zeolite ammonia remover, Bio-Chem Zorb, and there's a nitra-zorb pouch.

Course mechanical (the pads made for it), fine mechanical/polishing (polyester pillow stuffing crammed in as tight as I can), biological (Biomax). Water goes through in this order.
 
I have sponges (the ones that came with it) in the bottom, ceramic rings or pot scrubbers in the middle, and polyfill in teh top.
 
I would have all mechanical before the biological so the bacteria are dealing with the cleanest water possible and not being clogged by the debris that the mechanical should be collecting.
 
Carbon, and a foam sleeve around the container. Mag 350........:)
 
i use the foams and then ehfimech for bio, but I just snagged 4L of seachem matrix which I'll be using in the last compartments
 
When using Bio-Media does it matter which is choosen? Does the bacteria stick better to one of the other?

There are ceramic rings, foam-like stars, bio-balls....is there a difference of which holds bacteria better???
 
I'd get Seachem Matrix

Its very cheap, and the 4L box (~$24) on Big Al's will fill the top 2 compartments, if you want it to be bio.
