If I had a large plant mass (subjective term for sure) ,and few fishes,,then an air bubbler would not be high on my must have list for the plant's can produce enough oxygen during the day, to easily carry the fish through the night without fear of low oxygen level's.
If I had same large plant mass,and heavily stocked tank full of fishes however,then I might opt to run the air bubbler or air stone only at night when plant's are using up oxygen that they may need, and fishes might find it lacking.
If I had very few plant's ,very few fish,the filter moving water throughout the tank would be all I would want for lot's of folk's run fish only tank's with no plant's, in just such a way.
