Absolutely impossible for me to detect the titration color change.

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.

it's not the easiest, and short BUT very accurate.
I checked with a lab standard solution.
and got +5 PPM.

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...
