When I checked our your link Sustain did NOT list the ingredients in their chlorinators, just lots of useless adjectives. They didn't say "Cal-Hypo" or "Tri-chlor".

As soon as chemical companies get vague about what they are putting in their chemicals, they ain't going in MY water! My kids get that water in their mouths, they swallow some and NOTHING gets added by me that I don't know EXACTLY what's in it. Ever. EVER!
