That's an excellent point. I will update the documentation accordingly.

Would the prevailing temperature affect the treatment time of the chlorinated water?


According to http://www.water-research.net/watertreatment/chlorination.htm, "Contact time must increase under conditions of low water temperature or high pH (alkalinity)." Unfortunately, I don't seem to be able to find a cookbook that says how much more time at what temperatures.
