The topic of aeration and dissolved oxygen is very complex with methods ranging from non-mechanical and passive designs to the other extreme of injecting pure oxygen or other chemicals to artificially increase DO to supersaturated concentrations. I prefer cheap, low-tech or no-tech methods especially teaching the plants to specialize root zones to gather oxygen instead of relying on machines that can fail! I always try to think, if I was in a 3rd world country with little to no access to electricity or water or other materials, how the heck could I build this system and feed myself? Not to mention I'm cheap, and it's a cheaper hobby that way!
