Description
Biological filtration utilizes living organisms to remove substances from aquatic systems as a natural result of their respiration and metabolic processes. This mode of filtration is at work in any aquarium system housing live organisms. Though microbes (e. g. bacteria) are arguably responsible for the majority of nutrient-remineralization that takes place, oceanographic studies have shown that up to 90% of the dissolved organic carbon present in seawater may be assimilated by planktonic bacteri
