# Oxygen, where the water needs it

There is no proprietary mystery here. The mechanism is ordinary physics and biology, and these pages lay it out clearly enough to repeat to someone else and precisely enough to check.

*Summer stratification: a warm, oxygen-rich surface layer sits over a cold, oxygen-poor bottom. Illustration, not to scale.*

- [What are nanobubbles Oxygen bubbles roughly 2,500 times smaller than a grain of salt: small enough to stay suspended for weeks instead of rising and bursting.](https://alchemal.com/technology/nanobubbles/)
- [Nanobubbles vs aeration Your aerator works at the surface, and the problem forms at the bottom. What each one does, and where a fountain still earns its place.](https://alchemal.com/technology/nanobubbles-vs-aeration/)
- [Nanobubbles vs chemicals Algaecides work as labeled and feed the next bloom anyway. Here is how that cycle runs and what a structural exit looks like.](https://alchemal.com/technology/nanobubbles-vs-chemicals/)
- [Muck: dredging vs digestion Dredging excavates the layer; oxygenation digests the organic part in place over seasons. Which fits depends on what your muck is made of.](https://alchemal.com/technology/nanobubbles-vs-dredging/)
- [The N-Series One platform sized to your water, from a pond unit that plugs into a standard outlet to lagoon duty. Which unit fits your water, and how to read every number we publish.](https://alchemal.com/technology/n-series/)
- [How we measure The methodology behind every number on this site: sensors, stations, calibration, the before/after standard, and the claims ladder itself.](https://alchemal.com/technology/how-we-measure/)
