what do you want it to do?
As far as i know the purpose of a fluidized bed is t ogenerate a huge surface area for aerobic bacteria. The smaller the particle size the larger the surface area. If bacterial growth is all you need/want then sea sand should do the trick.

Hi Lindsay - why would you want to use a Fluidized bed filter for? It does the same job as the top +-5-6cm of your Deep Sand Bed? And you liverock?

The only thing I would suggest using a FBF for, would be to add phosphate remover material (ie. SeaChem's PhosGuard) to it.... or perhaps activated charcoal?

Ive heard that this is mpre tricky and problematic than beneficial

Huge closed bio sytem that crashes and needs to reset when there is a stop to thru flow -- very quick die off!!!!

i know they used in fermentation where they need massive bio load, and there the substrate gets replaced often. I guess a fluidized bed would work in freshwater, i think in a marine setup it should be reserved for carbon/phopshate removal as Jaquesb pointed out.
