I've tested 5 times now and still no idea. I these potassium test kits are BRUTAL

I'll cut dosing the kbalanceI and watch for improvement

Are u using the zeovit potassium test kit ? I hated it bought an Elos one a while back but havnt used it yet I can try it later on and if its easier feel free to come grab it

I am using the kz one. I heard the elos is better. I may take you up on that.

I tried to look up the kz test kit to see if I could help and the best thing I found was the test is cr•p. lol. Not one good review on it

I agree lol its awful

I Think it probably is potassium overdosing but what I cant figure out is that even the white tips have great polyp extension, I thought any tip burning would have no polyps at all

If you're looking to buy another Potassium test kit, I've used the Elos recently
I don't like the lack of range between 3-400ppm
It's hard to know what your results are
Look at how small the range is

If you can get your hands on one, the Salifert is supposed to be easier to use, and has a more defined range as it uses the titration technique
Count the drops and there's your reading
