The first time I changed water in my 90g heavily planted (cycled) tank
many years ago I wasn't sure if I had chlorine or chloramine
either. So I treated it with some inexpensive chlorine-only treatment
I picked up at my LFS (I cannot recall the brand). Within an hour of a
30% water change my fish we're showing major stress, and before the
day was over I lost over half of them. To this day I'm not sure
exactly what happened (I am basically chemistry-challenged), but the
problem had something to do with chloramine, which I discovered the
next day is what our water dept. uses in the water. The next water
change I used Amquel, which handles chloramines, and I have been a
satisfied customer ever since.
