I'm confused with ph
.. if I look at it up against the color chart on it's side it looks like it lowered a bit to 8.0.. but if I look at it's bottom..it looks more like 8.2
is there an easier way to compare colors? I've been told to look up through the bottom for a more accurate reading.. but on the back of the color card it says compare on the card with the vial on it's side... any suggestions? and if I am reading it right on it's side.. why has my ph
lowered and how do I raise it?
