I'm not prepared to present a water chemistry arguement at the moment.
I'll just say that I routinely put fishes into thiosulfate-treated tap
water with no other treatment to filter or remove ammonia (such as in a
bucket or bag) and have never had any problems. I guess I am assuming that
our municipality uses chloramine (I believe it is the standard now), and I
know that the concentration varies widely. Sometimes the odor is
overwhelming as it comes out of the tap. Nasty! Maybe I should also say
that our water is never acidic, but rather tends to the alkaline/hard.
