    TF100 results question

    Just checked my water after tons of rain over the past 2 days. FC came up as 3. Decided to check for CC, I added the 5 drops of R-003 back to the solution and it turned pink. I then added 2 drops of the R-0871 before it went clear again. Does this mean that I have 1(ONE) part cc or .1(point 1) part CC? Is it time to shock if it is 1 (ONE) part total? The way I'm understanding it, if the upper limit of CC recommended here is .5 before shocking, even if you have to add just one drop to turn the pink solution back clear it's time to shock as you are already at .5 Thanks in advance guys.

    My understanding if you are at .5 or under no shocking is necessary.

    I would post a full set of results so the pros here can better help.

    It depends if you're using 10 or 25 ml sample.

    2 drops of the R-0871 after the R-0003 in a 10ml sample means a CC of 1 and you need to shock. Mynewpool is right anything more than .5 CC is shocking time!

    A full set of numbers would be nice too.

    Re: TF100 results question

    I used a 10 ml sample------the same one used for the FC test. Don't even see anything about using a larger sample. So you guys are saying even if you have to add only ONE drop of R-0871 to turn the solution back to clear that you're already at the CC max of .5 for shocking? That seems awfully sensitive to me and it also means you can't measure any CC lower than .5

    You can measure down to .2 but that isn't usually needed and uses a lot more reagent. If you want to knw how you can search for test kit instructions on one page and it steps through how to do it.

    From my understanding if you use the 10 mL sample and the instructions on the kit, 1 drop of R-0871 to turn back clear gives you a .5. If you have to add more than one drop you are above the .5.

    Re: TF100 results question

    If one drop turns it clear during the CC test, your CC is <= 0.5.
    I think the criterion for shocking is if CC is > 0.5, i.e. it takes more than one drop.
