Dosing potassium?

[shelburn61]

I see people mentioning K more and more, and I guess I'm out of the loop. Will I see better color from dosing K or KI alone or is it just used with the Z system? What's the story?

not sure but I have been using some from TM and it seems to help alittle. Not sure I need to get my test kit first to see what it measures and then I will adjust according to that and then post some results.
