Take ALL that Terry has said to heart! Again he does not mean to insult as he offers much of his time and knowledge on this forum daily... to all of us whether we have 30 years at this hobby or 30 days!
I could give you a mouthfull but I'll spare everyone...
What I DO want to offer is somewhat contorversial with the old salts out there but I have tried it in the past with some success.
To possibly save your current situation go call around and see if anyone carries the bacteria in the bottle stuff like:
the one I keep in the fridge for just in case emergencies if ever...

I am not sanctioning Dr. Foster's and Smith's site, just used it for quick reference tho I have ordered from them (as well as SWF.com) with no problems before...
So check around town at all the Fish Shops and see if they carry any of these or similar ones to get a quick handle on your toxicity levels!!!
AND go out and buy any cheap large container to mix new batches of water as you will need to continue to due a few more water changes short term also...
I QUARANTINE FANATICALLY!!!
Good Luck!
