Default Potassium test

Hi, I use Sallifert to test potassium.
I have had problems with my last tests, after 1 month they are measuring errors. Test result will be 360. Someone else has experienced this?

What test do you use? I only know about Salifert and Redsea, Redsea is much more expensive and more time demanding

If you use sea salt, cross test under the same weight

If necessary, measure against a reference and simply determine the correction factor.

Those test only last a short time. At least try cleaning out the vial properly
