Conflicting test results...........

We usually say that if 1/2 scoop turns the water pink, then that's enough.

Some time ago I read that one scoop was sufficient if it turned the sample pink. Out of curiosity I compared using one scoop vs two (as recommended in the Taylor instructions); both turned the sample pink and both resulted in the same FC measurement.

Yup. That's what we have been telling you all for years.
