Xinyou XY-280 Super Biochemical Aquarium Sponge Filter 9 Pack

The Xinyou XY-280 Super Biochemical Sponge Filter stands as the industry standard for reliable, low-flow aquatic filtration. Engineered specifically for breeding setups, fry-rearing environments, shrimp habitats, and quarantine systems, this air-driven internal filter delivers exceptional mechanical and biological filtration without generating harsh, disruptive currents that can stress or trap delicate livestock.

By combining high-density, bio-friendly poly-foam with an efficient air-uplift system, the XY-280 maximizes available surface area for beneficial nitrifying bacteria colonization while effectively trapping fine particulates to maintain pristine water clarity. Its heavily weighted composite base ensures the unit remains securely positioned on the substrate, completely eliminating the common buoyancy and tilting issues found in lesser replica brands.

Key Features

• Dual-Action Filtration: Seamlessly combines physical mechanical extraction of organic solid waste with massive biological surface optimization for rapid ammonia and nitrite breakdown.
• 100% Livestock Safe Design: Completely eliminates mechanical impellers or high-suction intakes, making it perfectly safe for newborn fry, larval shrimp, and long-finned species like Bettas.
• High-Capacity Aeration: The internal airlift mechanism gently breaks the water surface tension, heavily increasing dissolved oxygen levels while driving uniform gas exchange.
• Weighted Anti-Float Base: Specially weighted ballast foundation keeps the entire unit firmly anchored to the glass bottom or substrate floor without moving.
• Zero-Friction Maintenance: Retains structural density through repeated cleaning cycles. The sponge cylinder easily slides off the core assembly for simple, chemical-free rinsing.
