So i want to start looking into buying a pH meter for my tank. What should I be looking for specs wise? Any models/brands recommended?

In this case, you want a pH controller (pH monitor).

A pH meter will only measure the pH.

With the controller, the pH meter will read the pH and then allow the solenoid (that is connected to your CO2) to open/close dependent on the pH.
