My gallon treated with 15ml PH down, as the guy said. My reading was 3.2 for the treated water??!!! No way!
Can you guys make a gallon up with tap water and add 15ml, 1 Tbl, then tell me what your reading is??
I do the same thing with my PH down, add 15ml to a gallon of water.
then I use that gallon as PH down, a little at a time.
