Aquarium Beneficial Bacteria. Furthermore, when there is a lot of oxygen in a fish tank, beneficial bacteria grow rapidly, leading to quicker nitrogen cycle formation. Adding this beneficial aquarium bacteria will give a tank a “head start” with the process of breaking down organic matter.
Seed a tank with good bacteria. While the procedure is not unusual, the new tank can be seeded to begin doing it later in the month, thus allowing for larger fish in the new aquarium sooner. They are responsible for the smooth running of the aquarium.
