Both fluidized bed filters and wet/dry filters are useful primarily
for their biological action. I.e., they provide a home for the bacteria
that convert ammonia to nitrate. In a tank without plants, this is
very important, since nitrate is far less toxic than ammonia. In a
well-planted tank, the plants will be using all the ammonia that they
can get, and additional biological filtration will just provide
competition for the ammonia.
Of the two, the wet/dry is probably a better bet, since it has one
major benefit: a sump. This is a great place to put your heater,
CO2 reactor, etc.
