When you start with a high CC and then shock, what happens to the CC? Does the FC get rid of the CC like it does bacteria and such?

The buest guess chart for a safe shock level lists the FC (as I would expect), should the TC be considered at all for safe levels for vinyl liners? In other words, if you have a high CC and it takes a high amount of FC to shock would a level of 15 FC + 10 CC =25TC be harmful for the liner?

THANKS!
