kz potassium test kit

[Johnny Reefer]

I haven't used mine in awhile, so specifics escape me, but...don't get caught up in the instructions. They are convuluted (sp?) and say far more than they need to.

Yeah..I love to guess what level of K I have in my tanks when use the KZ kit...one glass of wine usually brings it up a few points though
