    Testing for CC's

    Usually I test and put everything away immediately. There have been a few occasions where I've had to walk away for a minute or two before cleaning up. I noticed that on these occasions, my clear 0 CC sample has taken on a pinkish tinge. So, I am wondering if I am correct in reading the sample immediately or if it needs some time to show if there are truly some CC present.

    Just wondering, thanks!

    The FAS-DPD chlorine test will turn pink again if you leave it for a couple of minutes. The immediate reading is the one that counts. Ignore the pink after it has been sitting for a while.
