    first time testing with tf-100

    When testing for CC.... i put the 5 drops in mixing while adding. it did not turn pink and I did not immediately dump the water. I went on to complete another test and when I looked again at the cylinder the liquid not had turned a slight pink. long am I supposed to wait after adding solutions and mixing before reading results?

    You should read the test within a few seconds of adding the drops. It's common for the test to turn back pink after a little while. Don't worry about it.
