The XINYOU XY-280 Super Biochemical Sponge Filter is an air-driven aquarium filtration system designed to provide effective mechanical and biological filtration. Its multi-layer porous sponge captures suspended particles, fish waste, and uneaten food, while providing a large surface area for beneficial nitrifying bacteria. These bacteria help break down toxic ammonia and nitrite, supporting a healthier and more stable aquarium environment.
The filter uses an airlift system to draw aquarium water through the sponge and return filtered water to the tank. Its gentle water flow makes it suitable for discus aquariums, tropical fish tanks, breeding setups, and fry-rearing tanks where strong currents may be undesirable. The sponge also promotes water circulation and oxygen exchange. Its reusable design makes routine maintenance straightforward.
**Directions for Use:** Connect the filter to a compatible external aquarium air pump using airline tubing. Position the filter fully underwater and switch on the pump to begin filtration. Before first use, soak the sponge in aquarium water for approximately 5 minutes. During maintenance, gently rinse the sponge in removed aquarium water only; do not use hot water, soap, or untreated tap water, as these can damage beneficial bacteria.
