Okay well I looked up the PH of Ice Mountain bottled water.. says its 6.98 on the internet...

so i added about a little less of half of a bottle cap of ph down to hopefully bring it around 5.5... I have no way of measuring what the PH is after though

does that amount for about 1 and a half bottles of drinking water seem right to bring it from 7 to 5.5?
