You may have chloramin which does not gas off like chlorine. Many
water utilities use it now.


and I got a 4 oz bottle of Stress Coat, primarily for the
dechlorinator factor. I added 15 ml, measured with a syringe. I've been
reading about this product on Google, and it seems some people have had a
bad experience with this, and prefer other products over it.

Stress Coat works fine as a dechlorinator, but is expensive for what
you get. Seachem Prime for example only needs a few drops per
gallon. The "coat" part of StressCoat is probably not necessary. Use
what you have, and buy better dechlorinator next time. (I used the
stuff for years until I knew better.)
