How Do I Work Out The Ppm Of Co2 In My Tank

[Gordon88]

Ok i currently run a pressurized CO2 system in my 190l tank, i am running it at one bubble per second through the bubble counter.
I know the recommended dosage of CO2 for a tank is around 25-30ppm.
I want to know how i work out the ppm of CO2 in my tank.

Can anyone help me please.

Thanks

all you need to do is measure your ph and kh then use this
co2 calc

ok i have done it and it has come out as 16g/l of CO2.

Is this 16 ppm then??

Thanks
