Brown dust algae can provide a natural filtration mechanism and produce interesting patterns of growth as well as helps the photosynthetic organism that contributes energy and nutrients to the aquarium creatures.
Additionally, brown algae can remove carbon dioxide (CO2) from the water and release pure oxygen, helping to maintain a healthy environment for fish and coral.
