Using the TF100 test to check FC I ran the test using the speedstir I added drops till the water turned clear. I walked away for a few minutes and when I can back I could now see a little pink. Did I not add enough drops or could it change just sitting there?

Once it turns clear, the test is over, dispose of the sample or continue to your CC test. They will turn back pink if you let them sit.
