Salifert has stated on a few forums that a new, easy to use Potassium test kit will be hitting shelves by the end of March. The new test will have an resolution of 15 ppm. Salifert is boasting the test sharp contrast in colors making it easy to read. Further more the test is said to take 90 seconds. Salifert is also working on a Potassium test with a lower resolution (higher sensitivity) of 4 to 5 ppm. This test is expected out “at a later date”.
