CO2 sensors. You can measure CO2 right above the water to determine the CO2 in the water or you can water proof the Sensor and use a CO2 permeable membrane and submerge it in the water. The underwater CO2 sensors are used by scientists and cost thousands of dollars.

You can use a drop checker with a controlled kh solution to give you a decent estimate of CO2. The ph , kh, co2 relationship does work in a controlled environment like a drop checker.

As long as your plants are growing and pearling, go with it, as long as the fish don't die from OD.
