Like he said, if there is enough of a reserve of FC in the water to handle the organic load there will be no CC formed. This can happen in a perfect world. In the real world if there is over .5 ppm CC then you need to shock to get rid of it becase in the real world things like rainstorms happen , the dog jumps in the pool, the 3 year old decides she doesn't want to leave the water to tinkle, the teenages invite 30 friends over for a pool party, and so on!
Too many people know too much about me!

The underlying chemistry is complicated and confusing and isn't super-necessary to follow. Just like you don't need to know the bio-chemistry and physics involved in tying shoelaces, you just need to know "Form the bow..." If you stay on top of your pool test numbers, and stay ahead of problems, you don't have problems.
