ARRGH!!! QT mistake with Chloramine

ugh!

I've been running a 5G quarantine tank.. and been doing lots of water
changes both due to medication and persistant ammonia level (and zero
nitrite/nitrate, so the tank is no where near being cycled).

I did add a used filter from one of my cycled tanks when I set up the
Q-tank, but no help.. and kept changing water after water, hoping to
reduce the darned ammonia level.

and I happened to read the stupid label of my water conditioner that
I've been using for the past 4 years.. it only breaks the chloramine
bond but not neutralize ammonia!!!

argh!!! so by changing more water, I was just adding more ammonia. It
was never an issue with the main tank because of a large biofilter
colony, heavily planted, etc.. so whatever ammonia I dumped using a
"chloramine bond braking water conditioner" just got sucked up, and
never registered on my ammonia test kit. argh!!!

luckily I had a bottle of Amquel handy, so i just dumped that in, but
I'm afraid the damage has already been done...

my poor gouramis that's been stressed through medication is further
stressed with ammonia. the original problem that they were being
treated seem to be finally abating using Furan-2, but I think the
ammonia is doing them in :-(

is there no hope once the ammonia has done the damage to their gills?

waaahhh

I feel like a total idiot. I think I'm going to throw out my water
conditioners now (my city turned chloramine in the past year or so.. so
this is more of a recent thing), and go stock up on Seachem Prime (seem
to be the best on the market for price/performance?)

my poor gouramis!!! I feel awful :-(
