As I understand it, the amount of ammonia that is contained in the
chloramine in drinking water is insignificant compared to the ammonia
produced by a living fish. Thus, simple dilution and biological filtration
will render it harmless once it is detached from the chlorine by the
thiosulfate. The chlorine, on the other hand, is deadly. That's why it's
used to kill bacteria, etc. The ammonia simply makes the chlorine more
stable in solution, preventing it from off-gassing quickly.
