    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?

    if bio-balls are considered nitrate factories, what would a fluidized bed do to nitrate levels?

    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.
