2-Piece Aquarium Air Pump Filter Kit, Dual Aquarium Filter with 4 Replacement Sponges for Biological and Mechanical Filtration

Safe Material: This aquarium sponge filter is made of high-quality plastic and sponge, which is non-toxic and environmentally friendly. The sponge is eco-friendly and will not harm fish.

Improved Water Quality: The pores of the sponge filter have a large surface area on which aerobic bacteria can multiply. By cultivating nitrifying bacteria, you achieve excellent biological filtration in your tank. Furthermore, your aquarium water remains super clean and crystal clear.

Easy Installation: The water outlet pipe on the sponge filter is adjustable, allowing you to change the direction and height of the water flow. Compatible with two suction cups, it can be installed anywhere, easily hidden on the back wall of the aquarium, and can also be used as a pre-filter or secondary filter.

Removable Sponges: You can easily remove the sponge from the filter for cleaning or replacement.

Use water from the tank instead of tap water to clean it during water changes. Simply rinse and squeeze several times until the water runs clear. Widely Used: This aquarium filter is small and easy to hide behind plants. Perfect for shrimp tanks, bedding tanks, breeding tanks, turtles, goldfish, discus, river crabs, fish, fry, or other fish. Removes floating particles and pollutants from aquarium water, increases oxygen levels, and ensures clear water and a clean aquarium environment.
