Let the TA settle around 60 and only raise it back to 60 when it goes below 60.
Bleach doesn't cause any net change in the PH. Adding bleach raises the PH for a short while, and it then goes down again as the chlorine get used up.
If "Ch" is chlorine, your chlorine level is too low. With a SWG, you should keep FC at 3 or higher. Without a SWG it should be 5 or higher.
