Perhaps I may be permitted to comment, just so the OP is clear on what we are now babbling on about.
All fish, plants and some bacteria respire continually, taking in oxygen and releasing CO2. Even plants. And it is 24/7. Obviously less respiration occurs with fish at night because they are less active (except the nocturnal species, obviously).
CO2 is also continually being produced by the breakdown of organics by bacteria. This is normally where most of the CO2 comes from, in a healthy balanced aquarium [natural, non-CO2 diffusion]. Again, this is 24/7 too.
Any significant disturbance of the water surface will tend to increase the gaseous exchange. Oxygen is brought into the water, and CO2 is driven out. While there are some sources that suggest the reverse in non-CO2 diffused tanks, there is no evidence of this, and most of us still hold the logic that any water surface disturbance is likely to drive out CO2 because there will be more in the water than in the air, generally.
So I would not promote surface disturbance to excess, and certainly not use any bubblers, air stones, etc. in the tank itself, aside from the filter. There is no need. There will never be a shortage of Oxygen except when something is seriously amiss, and there is still evidence of CO2 being driven out.
