Borate measuring woes

[aseigler]

I don't know if I have a special kind of colorblindness or what, but I have a really tough time distinguishing between the colors on the borate and the PH tests. I can tell the difference between the two furthest extremes, but I cannot see the difference between close together colors, they look the same.

I get the basic idea of this test. If it is pink, it has less, when it starts turning just a little bit orange, you hit 50. So the idea is to hit 50. I don't think I am dark pink enough to be 0, I think I am closer to 30. But am I at 25, 35, or 45?

I agree, close to 30. I would add about 15 ppm then see where you are at. Being right at 50 is not important. My understanding is you need to be at least 30 ppm to see most of the benefits of borates.
