the PH of the water is much much much more important than its chlorine or chloramine content.do not let your water sit overnight.
seventhchild Reviewed by seventhchild on . WATER QUESTIONS? Hello, there is a theory that you should let tap water sit out for 24-48 hrs before using it, my question is if you let it sit out covered or sealed (I.E. old plastic milk containers with the cap on) is it doing any good, or does it need to sit uncovered? newbie thanks!;) Rating: 5
