Biological Filtration
Biological filtration is a process in which microorganisms, such as bacteria, break down organic matter present in water or air. These microorganisms convert harmful substances into less harmful ones through natural biological processes, ultimately helping to purify the environment. In aquatic systems, biological filtration plays a crucial role in maintaining water quality by removing ammonia and nitrites, which are toxic to aquatic organisms. In aquariums, biological filtration is typically achieved through the use of biological filter media, such as ceramic rings or bio balls, which provide a large surface area for beneficial bacteria to colonize and thrive.
