    can you fill the Chlorine bottle to 5 mil rather then 10

    So Im slamming
    I have high CYA 80 (SWG)
    I thought I read somewhere when its high Chlorine levels you can read at 5mil and double it, saving form using 10mil and more drops

    Or am I just going to eat up all of my chlorine test kit

    Hmmmm... interesting idea. I don't know the answer but it would be interesting and useful if you tried it at the same time and see how the results look?

    the accuracy goes down, I think is the issue, so if you're going to do that, set your target FC a bit higher to compensate for testing error.

    Yes, a 5ml sample will result in a reading equal to 1ppm per drop. In the middle of a SLAM this is fine, but make sure when you perform the OCLT that you use the 10 ml sample for both the before and after readings.

    Cool
    I will see what happens tonight when I get home

    I just checked the TFT site and R-0871 (2 0z) FAS/DPD Reagent is only $10 or so
    I may just order extra if I get too low
    Hope this slam dosent take too long
