Hygger Aquarium Sponge Filter 20-55 Gallon | Air-Powered Filter for Breeding, Fry & Shrimp

Dual filtration for clear water

The Hygger Aquarium Sponge Filter is a compact, air-driven filtration solution designed for low-flow setups. It combines a circular bio cotton layer with a bio-ceramic ball chamber to deliver mechanical and biological filtration, making it well-suited for betta, guppy, shrimp, snail, and fry environments.

Why this filter stands out

Beyond basic filtration, this unit supports gentle aeration and easy maintenance. The integrated bubble stone helps boost dissolved oxygen, while the media chamber supports beneficial bacteria through bio ceramic material. The result is steady water quality that can support delicate fry and breeding setups without aggressive flow.

• Precision Double Filtration: mechanical capture via bio cotton and biological processing with bio ceramic balls.
• Air-driven operation: water movement is generated by rising bubbles, promoting gentle circulation.
• Built-in bubble stone: increases dissolved oxygen and provides visible aeration.
• Easy media changes: the filter chamber detaches and accepts different media as needed.
• Two sponges included: a spare is ready for quick replacement during maintenance.

Key features and practical use

• Versatile setup – ideal as a primary filter for 5–55 gallon tanks or as a pre-filter for other systems.
• Auxiliary capability – can support larger tanks when additional filtration is desired.
• Low-stress filtration – designed for delicate species and breeding environments where strong currents are not desirable.

Sizes and tank compatibility

Three sizes help match tank dimensions and depth:

• Small: 2.9" W x 4.1" H for 5–20 gallon tanks (up to ~14" depth).
• Medium: 2.9" W x 6" H for 20–55 gallon tanks (up to ~19.7" depth).
• Large: 3.9" W x 6.4" H for 55–125 gallon tanks (up to ~26.4" depth).

Use and maintenance

• Before first use, keep one sponge on the filter and reserve the other for quick changeouts.
• The filter container is detachable, allowing media swaps as your tank needs evolve.
• Connect to an air pump, then squeeze the sponge until it fills with water so it sinks to the tank bottom.
• Rinse the sponges with tank water every 2–4 weeks to maintain optimal flow.
