Hmmm, had never considered that prospect. I've been feeding this way for months with no ill effect however, so I'll continue. I'd imagine whatever chlorine does settle to be so little that it wouldn't make a difference.
I do rinse out the CBW with dechlorinated water daily because I keep them in that water for a few weeks.
