Sponge Filter for Small Fish Tanks: Breeding Fry, Shrimp, Snails, Betta (5-20 Gallon)

Precision Double Filtration Sponge Filter

Features and Benefits

• Unique Filtration System: The hygger sponge filter combines a circular bio cotton and a chamber base with bio ceramic balls for both mechanical and biological filtration.
• Ideal for Low Flow Aquaria: Suitable for breeding betta, guppy, shrimp, snail, and fish fry, or as a pre-filter for other systems.
• Air-Driven Technology: Powered by an air pump, this filter utilizes the water-lifting effect of rising bubbles to drive water flow through the filter sponge.
• Effective Water Purification: The filter sponge adsorbs excreta and residual bait, ensuring clear and healthy water quality.
• High-Density Pore Structure: Biochemical cotton has a high-density pore structure, efficiently trapping impurities and particles in the water.
• Bio Ceramic Balls for Cultivation: The filter chamber includes bio ceramic balls to break down waste and cultivate beneficial bacteria.
• Increased Dissolved Oxygen: A built-in small bubble stone at the bottom effectively increases dissolved oxygen content and generates numerous bubbles.

Use and Maintenance

• Dual Sponges Design: Includes two sponges. Remove one spare sponge before use and keep the other in the filter.
• Easy Detachable Container: The filter container is easy to detach and can be replaced with any other media as needed.
• Simple Installation: Hook up to an air pump and squeeze the sponge until it's full of water, then sink it to the bottom of the tank.
• Regular Cleaning: Wash the sponge approximately every 2-4 weeks using tank water to ensure optimal filtration.
