    How long do I wait to read the chlorine result

    Super basic question here. In the K 1000 test kit how long should I wait after putting the drops in to read the chlorine level? I've noticed that the color darkens significantly over time. Do I read it right after I put the drops in and invert it a few times or do I wait a few minutes and go with that color? The difference between the two is not insignificant usually 1 to 2 ppm

    Yes Jim, read it immediately. Most reagents begin to change color when they are allowed to sit idle.

    Pool School - OTO Chlorine Test

    This test measures TC, but if you watch closely it is possible to get a sense of the presence of CC. When you first add the drops of R-0600, the sample will immediately show the FC level. Then, over the next minute or so, it will drift up to the TC level. If you see the color changing, CC is present. Using the test in this way requires careful attention and a good ability to distinguish shades of yellow quickly.
    You need to invest in one of the Recommended Test Kits if you do not have one.
