Am I the only one who has a terrible time with some of the colors on the API Master Test Kit chart? For example, the High PH colors are extremely difficult for me to read. My water is either 7.4 or 8.0 and I honestly can't tell which shade of brown it is closer to! Obviously, that is quite a difference!
I also feel that, on my color chart at least, the 2 orange blocks for either 10 or 20 ppm of nitrates are EXACTLY the same! Maybe I'm a tad bit color blind, but I can't tell them apart at all.
Tell me its not just me!
