fluidized bed filter

Would a fluidized bed filter be a good substitute for LR because i dont have the money to get alot of LR.

I dont have much knowlege about it to make a good judgement but I would rather have The LR because of the small critters that come with it.

Just a brief look at them, and they seem to be more of a chemical filter than a bio-filter.....anyone please educate me here too.
Why not go with some base rock and add a little LR over time?
Rock does more than hosts the bio-filter, like dividing the tank for territory and providing hiding spaces as well as sleeping quarters...
I guess there is bio-filtration in there to, I found this:

It seems mostly to reference FW applications.
