Alkalinity and pH readings are not accurate. I also use a liquid test kit and these are way different readings. Makes me question the accuracy of the MPS readings, which is why I purchased these.

I’ve used all kinds of test strips and these are the best. The color and accuracy of alkalinity and pH are perfect for when I need to measure accurately. The strips measure MPS but detect chlorine as well. I rely on these test strips to give me the best accuracy. I even use other test strips to check, but always come back to compare with accuracy of these.
