Bubble size decides everything

Big bubbles race to the surface. Nano bubbles stay.

A bubble's size controls how long it stays underwater and how much oxygen it gives up on the way. Watch three ways of putting air into the same pond.

Large · 5 mm and up

Splashes surface water. Bubbles burst in seconds and most of the oxygen goes back to the air.

Fine · 1–3 mm

Better than splashing, but bubbles still rise and break at the surface within moments.

OxynityNano · under 1 micrometre

Too small to float up. They drift through the whole water column and keep releasing oxygen for hours.

Inside the generator

The pump draws pond water into the compact generator at operating flow.

Oxygen from the concentrator enters at the pump suction and mixes into the water under pressure.

Pressure and shear in the stainless steel mixer break the gas into stable sub-micron bubbles.

Bubbles stay suspended through the water column and keep raising dissolved oxygen.
