I had many people in the pool today. I knew it is going to be an overload so I have increased the SWG cycle. FC didn't fall below 6 all day.
At the end of the day my CC was 1 and I probably need to shock the pool again.
TA=90, CH=250, pH=7.5, CYA=35.
What should I do in order to avoid rising CC?
Thanks,
Avi.

CC takes time to break down. When you have a lot of people swimming it can build up fairly quickly. If you want to swim tomorrow, you should bring it up to shock level tonight. If you are done swimming for the weekend, just bring it up to the high end of the normal range and see how things are tomorrow.

You'll probably find that one day's exposure to sunlight with no or a light bather load will get your CC back to normal. Shocking just accelerates that process by increasing the active chlorine level.
