    Chlorine/CYA chart question

    I've been reading other posts in the forum about how much FC is too high to swim in. Am I right in assuming that it's safe to swim as long as my FC is less than shock value?

    My CYA is reading between 30-40 but it's a bit closer to 30 so if my FC were 10 (CC 0) and shock level is 12, it's safe to swim then?

    One of the threads I was reading was about a SWG pool so I was wondering if the same applies to Non SWG.

    Sorry to be a pest, but it seems the more I read, the more questions I have!

    Yes the water is safe to swim in up to shock level.

    Thanks for the quick reply. Yay! I'm at least understanding most of what I'm reading now. Thanks again!

    You're never a pest either! Lots of people available to answer questions. The ones some of us don't answer, we ALL learn from.
