I wait for at least one month to add fish. That way, everything gets a chance to grow in with absolutely no disturbances. Also, you can up the CO2 as much as you want to give the plants a head start for growth.
As for the aeration by Amano, yea, he just raises the pipes so it breaks the surface (too much work for me to do daily).
You should definitely turn the CO2 off at night, as it's simply just a waste of CO2. Just get a solenoid. You can even get an inline one if you are up for it.
