Correct me if I'm wrong or over simplifying it. Just trying to make sure I fully understand FC/CYA relationship. What I know (or think I know) I learned here so I know you guys can clarify and clear up anything I'm still cloudy on....
FC = Active Chlorine (unbound and available to immediately attack any nasties) + Reserve Chlorine (Chlorine bound to CYA but can still be tapped into, just not immediately).
If this is a true statement, does anyone know what percentage (assuming there is nothing in the pool at the moment for active chlorine to attack) is active and what percentage is reserve for any given CYA level?
