Nanobubbles vs your aerator: an honest comparison

What an aerator's bubble does

A bubble from a diffuser or fountain is millimeters wide. At that size it's strongly buoyant: it rockets to the surface in seconds and hands most of its oxygen back to the air instead of the water. A fountain oxygenates the water it can throw, and only that water. In shallow water, that can be enough. In anything deep enough to stratify, the bottom layer never sees it.

What a nanobubble does instead

Nanobubbles are roughly 2,500 times smaller than a grain of salt: small enough to be neutrally buoyant. They don't race to the surface; they stay suspended for weeks, dissolving their oxygen throughout the column, including at the sediment interface where the conditions behind algae, odor, and fish loss actually form.

What we concede, every time

• A fountain is beautiful, and it genuinely disturbs the surface: a real benefit against mosquitoes that our system does not provide.
• A diffuser is cheap, and better than nothing in shallow water.
• Sometimes the right system includes them. We'll say so in the plan.

What surface equipment cannot do is restore conditions at depth, and that's where every problem on our map begins. If your aerator was running during a fish kill, this is why: the crash formed below the water it could reach.

The numbers, when we publish them

Published research reports substantially higher oxygen-transfer efficiency for nanobubble systems than for conventional diffusers. We'll put the specific figures here with full citations (the claim in our words, the source, and what it does and doesn't show) rather than quote them loosely now. Our own installations are instrumented from day one; how we measure is already public.
