Bio-Sponge Filter S

This sponge filter is designed for shrimp tanks and other nano aquariums where a separate water pump is impractical. Keepers who want mechanical and biological filtration without adding a powered pump and the extra water movement it creates will find it suited to small setups.

Why it matters

• Air-powered operation: The filter is driven by an air pump, so no additional electric water pump is required. Rising air bubbles create the water flow through the filter and also aerate the water.
• Dense sponge pre-filtration: A thick sponge handles mechanical filtration, and the sponge material is described as bio-chemical, supporting both mechanical and chemical filtration.
• Modular media compartments: Dedicated containers accept bio-media, such as ceramic rings, or chemical media of the keeper's choice, allowing a second biological stage.
• Adjustable outlet and mounting: The outlet length can be adjusted, and suction cups hold the unit in place. A holder secures the air line.

What it works with

The filter fits nano and shrimp tanks and is driven by an air pump, which makes it a low-flow option for these setups. It can also be fitted to the inlet hose of an external filter as a prefilter, which reduces how often the external filter needs cleaning and supports its mechanical and biological filtration without significantly reducing flow.
