Description

Provide your fish with a clean and healthy environment using the Xilong XY-2811 Bio-Sponge Filter. This classic, air-driven filtration system is a favorite among breeders and shrimp keepers for its gentle yet effective performance. The high-density porous sponge provides a massive surface area for beneficial bacteria colonization, while the mechanical filtration traps fine debris without the risk of sucking in small fry or delicate invertebrates.

Key Features:

  • Superior Biological Filtration: The high-quality foam promotes the growth of nitrifying bacteria, essential for breaking down harmful ammonia and nitrites.

  • Fish & Shrimp Safe: The gentle suction makes it the perfect choice for breeding tanks, fry grow-out setups, and shrimp colonies.

  • Aeration & Oxygenation: Powered by an air pump (sold separately), it increases oxygen levels and improves gas exchange at the water's surface.

  • Weighted Base: Features a heavy-duty plastic base to keep the filter securely anchored at the bottom of your aquarium.

  • Silent Operation: When paired with a quality air pump, it provides a quiet, non-disruptive filtration solution for bedrooms or offices.

Feeding or usage guide

Preparation: Before first use, soak the sponge in aquarium water for 5–10 minutes and squeeze it several times to remove trapped air. This ensures the filter sinks and begins working immediately.

Installation: Connect the filter to an external air pump using standard 4mm airline tubing. Use a check valve to prevent water backflow if the pump is located below the water level.

Maintenance: Rinse and squeeze the sponge only in dechlorinated aquarium water during your regular water changes. Never use tap water, as the chlorine will kill the beneficial bacterial colony.

Replacement: For optimal performance, replace the sponge every 6 months or when it begins to lose its shape/density.

Compatibility: Best suited for small to medium-sized tanks or as a supplemental filter in larger setups.
