Because I have chlorinated water, I don't have any problems with weekly
changes of up to 25%, with some special cases getting 50% a week.
No experience with chloramines, so I would use a conditioner to be safe due
to the ammonia. Maybe someone could tell of their success/failure using
straight chloramine water for changes.

I never heard of it, and I can't see that it's worth the
risk. As you say, a few drops of dechlor is nearly free.

Thanx and a tip of the G-hat to Tinykins for pointing out
the need for this clarification. ;-)
