Contact your water supplier and find out for sure. No sense wasting money if
photographer's hypo will do the job (or overnight aereation). The smell
would indicate chlorine, for the stability of chloramine seems to also
greatly reduce the taste and odor (at least to my aged senses).
Some places have enough natural ammonia that the chloramine appears
naturally, BTW. I think J. F. Kuhns published a number of papers on this,
some years ago -- long before ammonia was deliberately being added. Your
local water analysis is vital in knowing what you are dealing with.

Sort of. It is a much less stable compound, AFAIK, so it works fine when
very fresh. Smell an older bottle and see what it turns into. ;-) Buy the
smallest container you can. I buy "Amquel" by the pint or quart, because it
keeps so well and is way cheaper.

Yep. And I have accidentally killed both Nothos and Rainbows at far less
than 1 mg/L, too. They are both really tough fish! The "Anubias" of the fish
No one knows the safe residual ammonia level, for sure, should you use hypo
on the above. Spotte has reported that 0.1 ppm (roughly 0.1 mg/L) is enough
to cause permanent gill damage and the resultant stunting of baby fish.
