Aquarium filters are critical components of both freshwater and marine aquaria. Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance. Furthermore,

Modern algae scrubber designs use upflowing air bubbles to generate turbulence; when illumination is added, algae grows inside the unit and consumes nutrients.
Commercial floating surface algae scrubber uses red LED lights and up-flowing air bubbles to cause algae to grow in the growth compartment. Inside of the compartment is lined with rough textures which enhance algal attachment; ribbons/strings allow further algal attachment.
Periodic removal of the algae that has grown inside of an algae scrubber removes excess nutrients (ammonia, nitrate, phosphate) from the aquarium water, thus providing the needed filtration.
