Hi all,

I'm just wondering if anyone has used any sort of substitute for ceramic rings. It strikes me that the shape shouldn't matter as much as overall surface on a microscopic scale. I'm thinking of using broken terra potta as a replacement. Any thoughts?
 
If you are looking for bacterial filtration I believe ceramic material may not provide the best surface area. But I may be wrong. Pot scrubbers are cheap and may provide more surface for the bacteria.
 
I use mostly lava rock meant for grills.
 
Army men? LOL
