I'm not an aeration pro either. FWIW I've always thought one of the main limitations on bubbles providing oxygen to surrounding water is time. The time bubbles are in contact with the water is very limited and transfer of O2 to water is not instantaneous. The main benefit is moving low DO water to the surface where it will be in contact with the atmosphere for an extended time.

Just my 1 cent.........
