Thread: CC = 0, is that good or bad?

    CC = 0, is that good or bad?

    I've tested my pool using the chlorine test in the TF-100. In all the times I've tested, my CC = 0. I can't seem to find a good answer as to whether this is good or bad? I think it's good, but would like to make sure.

    Thanks,

    That is a good thing.

    Excellent! Above .5 is bad. It's one of the indicators used to SLAM (Shock Level And Maintain) your pool.

    Great, thanks. So as long as this stays 0, no need to shock the pool (assuming FC is where I want it)

    I would add to the responses above - ".... as long as the FC is above the minimum for your CYA."

    0 CC with correct FC is good
    0 CC with 0 FC is bad

    It's a complex chemical process but simply put....CC is created anytime organic substances are oxidized by the chlorine in your pool (which is anytime someone gets in the pool). The catch is there needs to be enough additional FC to break down the CC and complete the process. If you are detecting 0 and you are maintaining the right FC....everything is happy.

    0 cc is only one of the indicators, if the water looks dull or cloudy, if you see visible algae, if you can't hold chlorine overnight then you might need to SLAM your pool. If everything looks good and you're holding chlorine overnight then your fine.
