Dissolved CO2 calculator in freshwater tanks

Instead of using drop checker, I' trying to calculate my CO2 levels using PH and KH.

I came across these few CO2 calculators:-
Aquarium CO2 Calculator
https://www.hamzasreef.com/Contents/...LevelFresh.php
CO2 In Your Aquarium | Aquarium Tools

Do you think its accurate? I'm doubting its accuracy because it didn't ask for the natural PH (ie before injecting CO2).

Does anybody know how to calculate dissolved CO2?

No method which uses only KH and pH readings will accurately determine the ppm of CO2 dissolved in typical planted aquarium water. The relationship of ppm of CO2 vs KH and pH is fixed only if there is nothing else in the water that affects the pH except CO2. And, typical planted tanks contain some tannic acid and/or other weak organic acids. When you use just the pH and KH readings to calculate the ppm of CO2 in the water you typically get a much too high number for the ppm of CO2.
