You want the CC to be zero. FC is the free chlorine available to fight stuff in the water. CC is combined chlorine, which is chlorine that's being used up by actively fighting stuff in the water. Those two combined = TC, your total chlorine. You want the total chlorine to be equal to free chlorine, which means there's no "stuff" in the water to fight, and therefore it's clean and sanitary.
