They call it "hypo". However, it doesn't really remove chlorine. It binds the chlorine, then releases it slowly over a day or so, and the chlorine dissipates to atmosphere. Then you're left with the hypo in your water. So why not just keep a bucket of water overnight and let the chlorine come out for less money?
