Fish Addict
I do water changes often without any dechlorinator and I don't have any problems with it, I think someone on here did a 85% water change with out and dechlorinator
My old bosses at the fish warehouse often do up to 20% changes without dechlorinating, and that's with chloramines in the water. They used to call me a worrywort because I wouldn't do it. Anything over 20% they treat.
