Matrix is great if you can find it on sale.
Most of my tanks are setup with ceramic rings, the Eheim stuff or matrix, then sponges, then polishing stuff like filter floss or pads and finally a pillow or two of Purigen.
Awesome, thanks. I think I'm going to order some Fluval Pre_Filter stuff for the mechanical stage:
...then pick up cheap pot scrubbers for the biological stage.
On top of that I have the white (fine?) filter pad that Eheim makes for my filter and the little black carbon pad sits atop that.
However, I still can't find a single document on Eheim's site, or in the user manual, which states exactly how much volume I have available for media in each section of the filter.
