For water purification can some one help me figure out how manuy drops of unactivated mms I would need to put into 5 gallons of water if I wanted to store it for emergency use for say 5 - 7 years? Also, should I wish to use activated mms, how may drops of activated mms (chlorine dioxide) would it take to do the same thing, and also with the activated mms would that be straight activated mms without being undiluted with water? Thanks
