EXLECO Sponge Aquarium Filter, Internal Filtr Aquarium with Air Tube, Small Aquarium Filter for 60-100L Small Fish Tank, Silent Foam Filter with Filter Material and Air Stone

• AQUARIUM FILTER WITH MORE OXYGEN CONTENT: The size of aquarium filter sponge is 11 x 7.5 cm, suitable for 60 to 100 liter aquariums. This aquarium filter for aquarium can be used with an air pump (not included). We provide an air hose for connecting the pump. The internal aquarium filter is operated by the air pump, which promotes the circulation of water through the air, thereby increasing the oxygen content in the water.
• MULTIPLE FILTRATION PROCESS: Aquarium filters combine mechanical and biological filtration. The internal aquarium filter can effectively absorb suspended particles and impurities, improving the quality of the water and keeping it clear. Bioceramic filter ball can absorb and decompose harmful substances, precipitate nitrifying bacteria and create a healthy environment for the organisms in the aquarium.
• WIDE RANGE OF APPLICATIONS: This aquarium sponge filter can meet the filtration and oxygen needs of betta fish, koi, shrimp, turtles and fish eggs. You can choose different filter patterns according to the number and density of fish.
• SMART DESIGN: The small aquarium filter has a transparent acrylic shell, which contains air stone and ceramic biofilter balls, which can effectively absorb suspended particles. The base of the silent foam filter is heavy, which allows the filter to sink to the bottom of the aquarium and prevent it from floating. The internal aquarium filter has a compact design, which saves space and can be easily hidden in the aquarium.
• CLEANING AND MAINTENANCE: Thanks to the removable design, you can disassemble the sponge aquarium filter and then clean or replace the sponge and ceramic biological filter balls. Separate the base from the main body first, then remove the plastic shell from the air hose interface. Make sure the air stone is not damaged during disassembly.

The aquarium sponge filter uses bubbles generated by an external air pump to suck water from the small holes found on the top and bottom covers of the filter. At the same time, the generated bubbles are released through the water outlet holes to form bubbles, promote water circulation and thus increase the oxygen content in the water. Suspended solids and impurities in the water are absorbed by the sponge aquarium filter. The physical adsorption of the filter sponge and the porous stone, and the biological decomposition of the ceramic filter ball, purify the water and keep it clear. At the same time, aquarium filters also promote the growth of nitrite bacteria, creating a healthy ecosystem in the aquarium. This aquarium filter works quietly and at low noise, ensuring a peaceful environment for aquarium creatures. It is generally suitable for aquariums with a capacity of 60 to 100 litres. Regular maintenance can extend the life of the silent foam filter. As the sponge filter and ceramic filter ball continuously absorb suspended solids, the accumulated pollutants not only affect the quality of the water, but also reduce the life of the water turtle filter. It is recommended to clean or replace it once a month.
