Red Sea Potassium Pro (K) Test Kit

SKU: 207095


  • 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...
