xElevate your aquarium filtration with Hygger
Designed for small to medium tanks, the Hygger Sponge Filter combines mechanical filtration with a robust biochemical filtration approach powered by a compact air pump. The result is a gentler water flow that helps absorb fine particles without creating strong currents, making it suitable for shrimp tanks, betta tanks, and juvenile fish alongside community setups.
Two replaceable media types—sponges and ceramic filter balls—work in tandem to trap debris while promoting beneficial microbe activity. The 4 sponges provide ample surface area for multi-layer filtration, while the ceramic balls add an extra tier of cleansing. You can easily remove and refresh sponge media, or swap in other compatible media as your tank evolves.
How it works
The system uses an air pump as the power source, with airflow controlling water movement. The design emphasizes a small, slow flow that minimizes disturbance to fish while maintaining water contact with the media. The outcome can be clearer water and a more stable micro-ecosystem as beneficial bacteria establish themselves on the sponges and ceramic media.
Ease of use and installation
Setup is straightforward with a 4 mm air hose connecting the air pump to the sponge filter. The outlet pipe is adjustable, allowing you to direct the water flow up, down, or sideways and to tailor water movement to your tank layout. Note that a compatible pump and air hose are required to complete the setup and achieve the intended flow.
The filter is designed for nearly silent operation and features a multi-layer filter cotton structure with a large surface area to maximize filtration without clogging. Secure suction cups and a 360-degree rotatable bottom ensure flexible placement and stable operation in varied tank shapes.
