when doing diy CO2, how do you test for CO2 ppm? i look at the bubbles as they come out and by the "eye-ball" method, there seems to be 1 bubble per do i know what that translates into??

He who dares to teach must never cease to learn.

30 gallon tall, pressurized CO2...killer lights
50 gallon long, killer filtration, low tech otherwise
