Why Aeration Helps Microbes Work Better

While there is a certainly ample evidence that beneficial bacteria products can work in ponds without supplemental aeration in them, the fact is, they tend to work much better when some form of aeration is in place.

The reason is simple. Most microbial formulations use strains of aerobic bacteria...meaning they thrive in higher oxygen environments, and don't do as well, in ponds lacking good dissolved oxygen levels.
