Salifert Potassium Test

[sbash]

Hi Folks,

I just got in a potassium test and it says the colour will turn blue, but I can't get it to turn blue. It turns green. I tried with two different systems...

Anyone else experience this?

TIA!

I don't think whether it looks blue or green particularly matters, if the test kit is milky white then develops the color at a certain # of drops, then I think it's probably ok.
Mine goes from white then develops light blue at 430-460.

I use this test just ran a test yesterday. It goes from Milkey white to kind of off yellow then to that blueish green color that you see.

Thanks guys!

It starts out cloudy white, then goes light green, if I keep dropping it just gets more green (which makes sense as it is starting to saturate)...

Okay, I'll assume it is accurate and carry on!
