    Help with understanding my CC level

    I had a CC level of 1.0 and shocked the pool down to a level of 0.0

    2 days later, with the help of rain, FC drifted down to 9.5 and I have a CC of 0.5 already today. No heavy swimming since the shock.

    Does this suggest algae, is it the rain, something else .... or is this normal? I don't know how long it would take to get the CC back to 1.0 but I figured I would ask and get a better understanding of what may be going on first. I hear lots here about people never shocking their pool and I want to get on that bus too!

    Thanks

    Evan

    Having CC show up as 0.5 on the test isn't a problem. Chances are that it is very near zero. If the pool gets lots of sunlight and you maintain the correct FC level, you don't usually get CC, or only a tiny bit that reads as 0.5 on the test. There could be something more complex going on, but until CC goes higher than 0.5 I wouldn't worry about it.

    Thanks Jason. I will keep an eye on it and take it from there. I don't typically get lots of sunlight, BTW.
