how do i read this
saw some water tester strips at home depot and i'm not sure how to read it. they want me to fill out something with adress, phone, email etc, then send in a photo of the strip... and im not willing to give them my information. does anybody know how to read this strip with a very brief explanation? is it okay to drink? is this strip a gimmick? should the colors be a perfect match to the printed paper?
