I too use AWT. And oddly enough our parameters are almost identical. Now, I have heard that they always show low in potassium. Hmmm? And to raise it. I bought a bottle of Pohls K-Balance potassium. Not cheap stuff. I dosed daily for a few weeks per the instructions. I had my water retested and found nothing had changed. Hmmmm? I bought a kit from Red Sea to test potassium. Too much of a pain to use. Maybe I should use potassium chloride instead to raise it? Any thoughts?
Also, on the results, it shows ionic calcium as being low. Yet, total calcium is high. Which is actually the desired measurement? Or how do you adjust one without negatively affecting the other?
