No - I had trouble with that one as well.

I use the LaMotte kit and it works well for me. Other people here report
good results with the Hach kit. Those two seem to be the only two that
consistently do well for iron.

I seem to recall at te beginning of this thread that the pH was "7.4+",
because 7.4 was the highest reading that this the test kit used could
report. People seem to be rsponding as though he said =7.4. Seems to me he
might just as easily be at 8.2, which would explain why his CO2 is
