XINYOU XY-2831 Air Pump Double Sponge Filter

Product details

The XINYOU XY-2831 Air Pump Double Sponge Filter is an aquarium filtration unit that uses a sponge medium driven by an air pump to provide both mechanical and biological filtration. In practice, it works by drawing water movement through the sponges, which helps remove fine debris while also giving beneficial bacteria surfaces to colonize. This makes it a practical choice for many freshwater setups—especially when you want stable biological filtration without strong suction that can stress small fish.

Features:

• Provides mechanical filtration by trapping suspended particles in the sponge
• Supports biological filtration by offering an ideal surface for bacterial colonization
• Designed around air-driven flow, which is typically gentle compared with many power filters
• Double-sponge design increases the available sponge area for filtration
• Helps avoid trapping fish fry, making it useful for breeding and spawning tanks
• Suitable for small freshwater community breeding setups such as Discus, Dwarf cichlids, guppies, and killifish (general guidance)

Specifications:

• Max tank size: 10 gallons
• Dimensions: 5" L x 1.8" W x 5.5" H
