I have been working on lowering my TA from 140 to 80 and am confused where I am at. I realize I still need to work it down some more. This is with the TFTestkit.
On the 8th drop after a good swirl it is still a solid green. On the 9th drop the solution turns this COLOR and on the tenth it looks closer to this COLOR. So is my TA 90 or 100?
