Hygger Sponge Filter for 20-55 Gallon Tanks - Ideal for Fry, Shrimp, Snails, Betta

Precision Double Filtration System

Hygger’s sponge filter is engineered to provide both mechanical and biological filtration for your aquarium. Ideal for low-flow breeding environments such as betta, guppy, shrimp, snail, and fish fry, it can also serve as a pre-filter for other filtration systems or an auxiliary for large tanks.

Working Principle

Powered by an air pump, this air-driven sponge filter leverages the water-lifting effect of rising bubbles. This mechanism drives water flow through the filter sponge, effectively adsorbing excreta and residual bait to purify the water.

Filtration

The bio-cotton sponge boasts a high-density pore structure, making it adept at capturing impurities and particles in the water. This ensures optimal filtration, maintaining clear and healthy water conditions.

Culture

The filter chamber is equipped with bio-ceramic balls, designed to break down waste and cultivate beneficial bacteria. This symbiotic environment supports the health of your aquarium inhabitants.

Aeration

A small bubble stone at the bottom of the filter effectively increases dissolved oxygen content. The continuous generation of bubbles ensures adequate aeration, benefiting both fish and water health.

Usage and Maintenance

• Sponges: For use, take out one spare sponge while keeping the other in the filter.
• Filter Container: Detachable and reusable, allowing for easy replacement of filter media.
• Installation: Connect to an air pump, fully saturate the sponge by squeezing it until it sinks to the bottom of the tank.
• Cleaning: Wash the sponge approximately every 2-4 weeks using tank water to ensure optimal performance.
