Beneficial Bacteria

Term from Aquarium Management industry explained for recruiters

Beneficial bacteria are tiny helpful organisms that are essential for maintaining healthy aquarium environments. They work like a natural cleaning crew, breaking down harmful waste products from fish and uneaten food into less harmful substances. In the aquarium industry, these bacteria are often called "good bacteria," "nitrifying bacteria," or "biological filtration." When someone mentions beneficial bacteria in their resume, they're typically referring to their experience in establishing and maintaining these crucial microscopic communities that keep aquarium water clean and safe for aquatic life.
