Testing for TA with the TF100 kit, when adding the reagent waiting for the water to turn from green to red, how far do you go? The water obviously turns red but continues to get even more red after a few more drops. Here is a real example I have currently. At 14 drops, the water turns red, but with drop 15, 16 and 17 it still changes color to a deeper red with each added drop, and at drop 18 it remains the same as where 17 left it. The way I understand it, this means a TA of 170, correct? I am under the impression you keep adding until the water stops changing, and not count the drop where it stops.... in my case the 17th drop equaling 170. Can someone please clarify for me? I am using acid to bring my TA down, started at ~290ish, so it is coming my way. Thanks
