About This

• Effective Filtration: This compact sponge filter uses an air pump to drive water through a fine sponge, effectively trapping debris, food scraps, and fish waste while simultaneously oxygenating the aquarium. The gentle water flow creates a healthy living environment for fish, achieving biological filtration
• Easy Installation: The compact design perfectly fits small aquariums from 0.5 gallons to 5 gallons. A strong suction cup secures it to either side of the aquarium glass without taking up valuable bottom space. An included check valve prevents backflow, protecting the air pump and ensuring safe operation
• Durable and Long-Lasting: The removable sponge can be rinsed in aquarium water (never tap water) and reused for months. It resists deformation and retains its shape even after multiple washes. For optimal performance, it is recommended to wash the sponge monthly and replace it every 4-5 months to maintain filtration effectiveness
• Three-Layer Filtration Design: The bottom layer prevents small fish or shrimp from being sucked into the filter, while the main sponge traps fine particles. This layered design ensures thorough mechanical and biological filtration, resulting in crystal-clear aquarium water
• Wide Compatibility: Suitable for small aquariums, spherical aquariums, nano aquariums, or any mini aquarium setup. Note: This sponge filter requires an air pump (not included). Package includes 1 sponge filter, 1 check valve, and 1 flexible air tube (approx. 100cm). Quiet operation makes it ideal for bedroom or office use
