When I looked into it years ago, the K test was based on turbidity and hard to read.

Is there an accurate and easy-to-use potassium test available nowadays?

I Like Salifert it seems to be pretty good and its based on colour change not turbidity

The problem is Salifert stopped making the Potassium test kit.

The last time our Salifert supplier was able to get it was March 2014.

Never thought about it until I used Zeovit balance K. I started seeeing better coloration and more grow on SPS. So I am planing on purchasing a test kit now.

I have been using Kent Trace Elements which has K in it, as well as a bunch of other stuff. Not sure if it helps, but since I just use IO for salt, thought a few extra elements supplements can't hurt. And it's cheap. My SPS growth and color has been good.
