Collection: External Aquarium Filters
Aquarium filters generally help generate flow, absorb substances that cause turbidity and enrich the water with oxygen. Beneficial bacteria that settle within the unit’s filter media help to break down and remove waste from aquarium inhabitants. External filters typically have different types of filter media in several layers throughout the filter unit. These filters operate outside of the aquarium and can be conveniently stored in a cabinet under the aquarium, making them easily accessible for maintenance.
