  • Good product but hard to use By Jay on 2/4/2015

    I also find it very difficult to detect the color change. I'm not sure when it's "blue enough". The color you see depends on the lighting where you do the test. Maybe I can take a picture of it and compare the colors in the image.

    Absolutely impossible for me to detect the titration color change.
  • Crystalized titrant By Deb on 12/7/2014

    This is the second time Bottle D has crystalized and become unusable. My first test kit arrived crystalized and the second test kit crystalized after just 2 tests. I kept everything contaminant free. Will never purchase again.
  • Very accurate By Ali on 8/1/2011

    it's not the easiest, and short BUT very accurate.
    I checked with a lab standard solution.
    and got +5 PPM.
  • Very Positive By radiata on 7/19/2011

    Tried my test kit for the first time today, and I'm impressed. Considering I've found and used only one other potassium kit, this one is preferable - it is more granular (doesn't rely on a subjective visual measurement, best described as "cloudiness"). The titration procedure is quite different that any Salifert titration you might be used to, but I did it right the first time - READ THE INSTRUCTIONS in the kit carefully.

    I will be certainly be buying the refills for this kit...
