You can do that, but if your TA rises faster than your pH, you may end up needing to switch to Borax after awhile. Kind of depends on how low your pH actually is. Since the pH tester only goes to 6.8, it could really be much lower than that.

#9 - Once you've added the polyquat, resume raising the pH until you reach a level of 7.4 - 7.6. At that point, your heater will no longer be 'under atttack'.
=> Use borax, till you've sustained a reasonable pH for a couple of days.
