haha... you have a point there.
info donation: Turning the CO2 off at night, even though the plants stop producing O2 from CO2, but rather CO2 is produced, still causes more of a pH swing than if you were to just leave the CO2 on. I would guess that the more surface movement, the more stable, but yeah... we want to keep the CO2 in the water.
