The whole point of chloramine is that it stays in the water longer.  Municipal
water companies add chlorine and chloramine to the water supply to fight of
deadly microorganisms.  Chloramine stays in the water longer, so it can be 
used in smaller quantities, saving money.  It has started to replace chlorine 
in a lot of water districts.

    CL> Are the products of dechlorinators totally benign?

At least the ones you can find in fish shops are.  I haven't heard of
any commercial ones that aren't safe.  If you're asking if they have
some side effects (like the pH-buffers), I haven't heard of or seen any.

If you're using a Python or something similar, just drip a little into
the tank while you're refilling, right at the water entry.  Make sure that
in the end, you've added the proper dose.  It won't be as safe as doing it 
in a bucket ahead of time, but it'll be much better than not doing it at all.
