Hmmm... I disagree slightly with this suggestion. I would suggest purchasing
a chloramine test kit FIRST. You may find the amounts of chloramine present
in your water to be negligible. I found none in my tap water and almost no
chlorine however, the water here is not typical of water elsewhere. I don't
know the correct procedure for dealing with chloramine as far as plants are
concerned however, ammonia is GOOD for plants in that it provides the
ammonium ion at medium to low pH (why pH should not be high in plant tanks).
I don't know what Amquel will do so I would be very leery of adding this. 
Perhaps there is some treatment that can be performed on chloramine water 
BEFORE you add it to a tank such as aging it one or two days. Even better 
would be to use rain water, distilled water or water from an RO unit. 

Anyone with practical experience in dealing with chloramine?
