From Project Gutenberg

Sodium bisulphite is a very efficient “antichlor,” only 1.46 parts being required to remove 1 part of chlorine, but owing to its instability the action is uncertain.

From Project Gutenberg

The action is an instantaneous one and it is consequently necessary that the germicidal action should be complete before the “antichlor” is added.
