How does this happen?  First, I keep my vinegar bath bucket separate from my salt and ro buckets (no rodi system due to extremely hard well water, filters would last a month).  So I go to top off 5 gallons, like I dip shit going, huh i wonder where that slight vinegar smell is coming from.  Well because I just radiate brilliant thoughts I continue to empty the bucket into my tank.  Then and only then did the bright rays of brilliance radiate on me, I started screaming no, no, God no like Steve Carell from the office.  Now, i will admit I should be wearing a drool guard and helmet, my allergies were going ape shit.  After sneezing 5x in a row, the aroma of vinegar whacked me in the face like a posses off silver back.  Then my screaming started.  Then my face looked a lot like Luke Skywalker after realizing his dad is Vader and that he tongue punched his own sister.
