How can I maintain a steady PH level?

The problem noted by meatloaf is that of rising pH, not falling pH. Your suggestion would be correct if the pH tends to drop over time since a higher TA will not only buffer the pH more but will tend to force the pH to rise or at least not fall so quickly over time.

However, since meatloaf's situation is that of rising pH, adding TA will only make that problem worse. This is because TA, specifically carbonates and more specifically carbon dioxide, is a SOURCE of rising pH itself since outgassing of carbon dioxide causes the pH to rise (with no change in TA for technical reasons I won't get into here).
