Potassium is one of the last frontiers for me. Tell me about your dosing regimen .. I'm a little hesitant to dose anything without testing. I do have a Potassium test kit (
this one) but it is inordinately the most difficult test kit to read. Basically, you're guessing the value based on how opaque the liquid is. I thought comparing colours was a subjective guess, this is worse!! Basically if in the end you're just guessing the overall value you can just guess without spending the cash.
However, I think it's more or less the only test kit for K and if you're anything like me, it's just a more comfort zone knowing you can test when you're actively dosing something (because it's generally imperative to know when to stop, IME).
Right now I am cleaning the glass every day. If I don't do it every day, it gets harder to clean with every day that goes by.
I do wonder about the K thing. It's just that I tested it and .. well, I think the end reading was about 400 (top of the scale). So either I guessed wrong, or K isn't really the issue.
