@ai6yr@mcnado Does it need to be from an UNopened bottle of chlorine? How does one compensate for a bottle that has been open for a while/ or expiration date? Just keep adding until you smell it in the treated water?
@ai6yr@mcnado After years of looking for the definitive answer, and not finding- I just looked again: • Locate a fresh liquid chlorine bleach or liquid chlorine bleach that is stored at room temperatures for less than one year. #chlorine#drinkingwater#treatedwater
