Latest issue - doing a water change in the sick tank - the filter finally seemed to kick in - brought ammonia (free) down to zero night before last. Didnt do a change yesterday. Decided to do a change just for principal. Found my ammonia (free and bound) way up. In the middle of a 11pm water change when I measured the ammonia of my untreated tap water - over 1. Treated - just better than my tank water (barely) - still measuring .6 free ammonia. Honestly - I am looking at my (untreated for the last 4 months) pool water again.
I think I am measuring the chloramines - which were supposed to be taken out of 'free' status by the water treatment (which I went at probably over 4 times recommended dose).
Could there be any way this stuff is not killing my fish even though the 'free' ammonia test (nO3) is picking them up?
Is the answer to switch to a different water conditioner?

I found out its not just me. A lady with a pond has drilled a well to fill it. She says she cant run more than 20 minutes of city water into it without affecting her fish (much bigger pond).
