Product description Transform your aquarium's ecosystem with this innovative S-size filter, perfectly designed for tanks between 5-91 litres. This sophisticated filtration system employs dual-stage purification through mechanical and biological processes. The high-density sponge effectively captures particulate matter, while the ceramic rings provide an ideal environment for beneficial bacteria cultivation. The filter operates using bubble-driven water flow, creating a gentle current that's ideal for sensitive aquatic life like shrimp, snails, and fish fry. Its compact design (7.3×11.2cm) efficiently combines filtration, oxygenation, and bacterial cultivation functions, maximising space utility in your aquarium. The filter features a detachable structure with spare sponges for convenient maintenance while preserving beneficial bacteria colonies. Requires an external 2-4W air pump (air tube sold separately). Perfect for breeding tanks housing fighting fish or guppies, shrimp habitats, fry isolation tanks, or as a supplementary pre-filter in larger aquarium systems. For optimal performance, soak the sponge before first use and clean every 2-4 weeks using tank water. Airflow can be adjusted via the pump valve for quieter night-time operation. Directions NO
