Airstone vs Fluming (DWC Hydroponics Dissolved Oxygen Experiments)

In this video I test the effectiveness of an airstone bubbler vs fluming (and compare it to a control with no techniques.)

The results are interesting, so make sure to stick around until the end. I've love some feedback on the experiment setup and anything I can do to further test the effectiveness of these techniques.
