FBF's only convert NH4 to NO3, nothing else. Plants use both of these forms of N. As far as water quality, unless you grossly over feed, have a very high bioload, you will not measure any NH4. Even Discus tanks run very clean and are much more bioload than even if you put 10-12 of these fish per Discus.
NH4 is the only thing that might cause an issue but not for the fish, for algae. The amount is so low to the fish, they are are ahppy all the time.
So plant tanks have the best water quality of almost all aquariums, except RO daily water changes etc and even there, some plant tank can have a better environment for the fish.
Get an Ehiem, ViaAqua, Rena etc.
