Should clarify.

There biggest gift to the aquarium world is cheap water flow. It pulls water up and exposes it to the air above, which causes it to pick up oxygen.

More airflow means more CO2 evaporates, if you're doing CO2 you want as little surface movement as possible without your fish gasping for air. If you leave the CO2 on at nighttime, you'll want an air pump that runs hard when the lights go off (to get rid of the unused CO2 that could cause a pH drop). If it's just DIY CO2 you can probably not worry a bout the last step, I wouldn't.
