I recall many years ago reading about trout below an overflowing dam that were dying. It was determined the trout were getting super-oxygenated and the investigators called it "bubble disease."

I suppose plain old air could be nano-bubbled, but then, you'd also be dissolving the other eighty percent of air, mostly nitrogen gas. Good? Bad?


I've been unable to find the air pressure required to generate micro and nano sized bubbles. So, I don't know if a regular aerator pump could be outfitted with a micro or nano sized bubbler.

I think there's two approaches to generating the bubbles: The nozzle may be attached to a high pressure water pump and the nozzle has an air hose open to the atmosphere (the water sucks air into the nozzle). Or, an air pump feeds the nozzle which also has holes before the bubble outlet to suck in water. Either way, generating a fine mix of water and air.

Pure oxygen or ozone generators may be expensive...in videos, a large cabinet is shown. Maybe an oxygen generator for breathing for disabled lung capacity...a hit on Medicare for a piece of pond equipment. LOL.
