Air Pump

[Spiceweasel69]

What about switching an air pump on at night when the solenoid for the co2 truns off? Thats what im thinking of doing? That way, the water gets oxygenated for the plants at night and the fish. In the morning it will turn off as the co2 injector turns on.

Whats the professional opinion in this idea??

If you turn off the air pump 2-3 hours before the CO[sub]2[/sub] starts then that can work well.
