Testing Co2?

[Ian H]

I just got a nutrafin co2 kit and im just wondering how i go about testing how much co2 will be in the water? i was told to get a gh & kh test kit but im not 100% sure about that?

Basically test your ph and your kh and you can figure out your c02 levels.

Here is a site that has a calculator just enter your values of ph and kh and it will tell you your c02 and it also has a cross reference chart.
