    Color transition is too faint to accurately measure K level. You can't measure anything over 400ppm. Very disappointed with the product. Do not waste your money

    anything between 350 or 400 looks the same. At 400, algae goes crazy. At 350, you're already way too low. Buy yourself a Salifert K test kit and save the trouble.
