But what about the addition of chlorine? Isn't it suppose to raise pH?
The 80 to 120 rule is based on incorrect information. It is not a useful guideline to follow. I would suggest that you base the TA on how the ph moves. If the ph rises, the TA is probably too high. If the ph drops, the TA is probably too low. When the ph remains stable, the TA is just right.
