I have few more questions about my new TF-100 kit:
1) In the instructions, some tests say to mix, others say to swirl. Can I just swirl for all tests, or does "mix" really mean to put the top on and thoroughly shake/mix for that particular step?
2) If I know roughly what my TA or CH will be, can I put a bunch of drops in to start with, swirl thoroughly, then finish by doing one drop at a time and swirling in between each one?
3) Tonight, for the first time that I've noticed, I discovered tiny purplish-colored "flakes" or particles in the solution while testing for CH. I believe this first started when the solution was phasing through purple, just before turning blue. Have you guys ever seen this, and does it mean anything in particular?
