the motor needs to be on. The theory is that the impeller will chop the bubbles into smaller bubbles.
There is no way to stop the creation of co2 from yeast. So let it bubble 24 hours. Don't try lifting the hose out of the water of a working yeast system. (While the outlet hose is under water, the water pressure holds pressure in the system. When the hose is lifted out of the water, the pressure is released and all the co2 escapes. You will need to build pressure up again before co2 bubbles will begin again.)
You can however put the filter used for the diffuser on the same timer as your lights and just let big bubbles float to the surface at night. (however diy co2 is very inefficient, and this is not necessary.)
