I've always had really good vision, and have never been diagnosed with any kind of color blindness, but I'm starting to question it.
Am I the only one that sees almost no color difference on the Nitrate card on the AP Master Test kit between 20, 40 and 80 ppm? I see a difference in the 160 reading, but not much of one. I ask because I just did a test and I'm falling somewhere in one of those three, but having a real hard time telling the difference.
I'm doing a PWC in an hour or so, nonetheless, so maybe I'll know which it was on the test afterwards, but I just don't have this problem with the other three tests in the kit.
