That's it in a nutshell. If you are using a pH controller you would plug the solenoid into the controller switch. Otherwise, plug it straight into your timer and have it turn off at night.
With a pH controller your BPS (flow of CO2
) is less important, because once you hit your max CO2
injection, the controller turns off the flow. Otherwise, you will need to balance your CO2
flow so to try and maintain a good level without killing everything in your tank.
