I'm wondering if anyone else has this problem. When I look at the Cl side of the Cl / pH tester in the PS200 kit, the 2, 3 and 5 levels all look the same shade and intensity of yellow. This is happening both in daylight and indoors, with the tester 2 inches from the white background of the PS200 case, or any other white background. If I look through the tester directly towards a light I can distinguish a slight difference between 3 and 5, but 2 and 3 still look the same. I've never tested positive for colorblindness but there's a first time for everything! Does anyone else have trouble distinguishing 2, 3 and 5 on the chart?
Thanks,
Steve
