What a nanobubble is, and why it matters to your pond
A plain explanation you can repeat, and check.
The plain answer
Nanobubbles are oxygen bubbles roughly 2,500 times smaller than a grain of salt. Bubbles that small behave differently from the ones your aerator makes: they're neutrally buoyant, so they don't rise and burst. They stay suspended in the water for weeks, giving up their oxygen where the water holds them. That includes the deep water and the sediment interface, where low oxygen sets the table for algae, odor, and fish loss.
Why the bottom matters more than the top
Nearly every problem on our problems index begins at depth: warm water stratifies, the bottom layer runs out of oxygen, and the sediment starts releasing the nutrients stored in it. Surface equipment can't reach that layer. Suspended nanobubbles can, which is why the same mechanism addresses algae, odor, and oxygen crashes.
What nanobubbles can't do
They are not a herbicide, and they are not an emergency response to a toxic bloom. They also won't fix clay turbidity or external nutrient dumping. Where the mechanism doesn't apply, we say so. Each problem page carries a "when this isn't the right fix" section for exactly that reason.
The full write-up is coming
This page will grow into the complete plain-English explainer, with the peer-reviewed citations presented in our citation-card format: the claim in our words, the source, and what the study does and doesn't show. Until each citation is compiled and checked, we'd rather publish less than paraphrase research into overclaim. The measurement side is already documented in how we measure.
