Nice idea, but I doubt he needs anymore oxygen being added to the

ability to carry CO2 which is needed for plant life. Often putting
too much O2 in will simply cause algee to thrive.

The jet from a venturi is said to stabilize the level of oxygen and
prevent over-oxygenation. Adequate planting is the key to algae
control.
