Pool testing for the color impaired

CYA test does not rely on a color change. Just see or not see a black dot.

There are CL meters, but they are expensive.

Only color test that I don't know a substitute for is TA.

I'm aware of the CYA test..... its a pass/fail. Lol.

The only point I was trying to make is that the pH test is the only test in a TF 100 that MOST colorblind people would have trouble with
