I don't have one but I'd like to talk about them too. As far as I know, it has several advantages over wet/dry filters. The media (sand) has more surface area and the water flows around all of it, allowing bacteria to colonize the complete surface area, compared to traditional wet/dry media wich often has spots that the water never reaches. Also, according to what I've read, the FBF never needs cleaning. There must be disadvantages as well but I guess I have to do some more research.

These are typically used in S/W setups. In most cases, the bed filter doesn't allow for the high turnover rates normally utilized in F/W setups. This is not ot say that you couldn't build a larger one, but the normal off-the-shelf ones aren't that impressive.

Seems like there's a lot of good info in that link. They might be worth the try.

Ok, so they don't have a very high flow rate and the BB dies quickly if the filter is turned off for too long. Also they need a very effective mechanical filter. Looks like supplemental filtering is definitely required when using one of these. Can't be beat in terms of biofiltering though apparently.

they are hard to get started when they stop

and you need a real powerful pump to run them 2500 lph more if you use a large sand filter
