Just get into the "add bleach in the PM, test in the AM" routine, till your FC is nearly equal your TC (ie, your combined chlorine is less than 1 ppm, when your free chlorine is greater than 5 ppm).

Don't try to hurry things up with a 'super' dose of chlorine.

Don't start adding other stuff, unless the pH gets way off. You can probably test pH accurately in the evening BEFORE you add more chlorine -- but when the chlorine is more than 5 ppm, your pH test is not necessarily accurate.

Just take your time, and stay on course.

Good luck,

Ben
