Once youve set up your drop checker, youll be able to fine tune your CO2 output so that the solution goes green. Expect it to be a bit blue/green first thing when the CO2 comes on. I have mine coming on 60 mins before the lights do, so that the plants can hit the ground running once they have light, and going off about an hour before the lights go off.

Thats the only really accurate way of setting up your CO2, noones going to be able to compare bubbles per second really, as there are too many variables to consider.
