CC is your bad chlorine. You don't want that. When you shock your pool <bring chlorine up to 18> it will distroy the bad CC.
You never want the CC over .5. Anything over that and you should shock the pool. To shock, you must hold it at shock level until:
Your pool loses less than 1 FC over night.
Your CC's are less than .5.
Your pool sparkles!
