It might not be necessary, but it's easier to calibrate your first CO2
system if you have some way to guage how many bubbles it's blowing relative
to how much the pH is moving around. That said, you can easily count bubbles
without any extra gear: just stick the CO2 line in the tank water for a
minute or two.
