Well, just make sure your filter has a compartment for bilogic substrate that is independent from the mechanical and /or chemical filtration. You want to avoid a filter that has only one cartridge, so that throwing out the dirty sponge takes all your biosubstrate with it.
A wet dry filter is every bit as good or better at ammonia and nitrite removal as a canister, and can support a huge bioload. It has the advantage of extreme aeration! All that water trickling over the biologic media will aerate the water many fold greater than surface agitation could provide. Of course, if you like live plants, all your water's co2
will be aerated out too, so its not used in planted tanks. It will also likely be noisier than a canister (the sound of water trickling and gurgling). You can also DIY
with wet dry filters, since they are basically all just a sump (bucket or smaller tank), overflow box in the tank (best to get a tank drilled with built in ones, IMO
), and a pump to send water back into the tank. The water going into the sump is poured over the biologic media to provide the wet dry aeration.
