sеra Siporax Mini biological filter media insert 270 g for aquarium filtration

sеra Siporax Mini biological filter media insert is supplied as a 270 g package of porous ceramic granules intended for use in aquarium filtration. The material is designed to provide a high surface area for colonization by beneficial nitrifying bacteria, supporting biological filtration processes that convert ammonia and nitrite into less harmful nitrate. The product is compatible with both freshwater and marine aquariums and can be placed in internal or external filters to enhance nitrification and contribute to more stable water parameters.

Advantages

The porous ceramic composition offers a large internal surface area that promotes rapid and sustained development of nitrifying bacterial colonies. Its granule form allows even water flow and uniform bacterial contact, helping to maintain efficient biological filtration without frequent replacement. The neutral material does not alter water chemistry and is suitable for continuous use in established filter systems.

Suitable for

• Freshwater aquariums requiring improved biological filtration
• Marine and reef tanks where stable nitrification is needed
• Internal power filters, canister filters and wet/dry systems
• New setups during biological maturation and established systems seeking improved stability

Key specifications

• Package content: 270 g of porous ceramic granules
• Material type: porous ceramic biological media
• Form factor: small granules suitable for filter baskets and media chambers
• Compatibility: suitable for freshwater and marine aquariums
• Function: promotes colonization of nitrifying bacteria for ammonia and nitrite conversion

How to use

Rinse the Siporax Mini granules briefly with dechlorinated water before placing them in the filter to remove any dust from packaging. Position the media in a dedicated media basket, chamber or compartment where water flow is steady but not turbulent; ensure even water distribution through the granules for optimal contact with dissolved wastes. For initial cycling, keep the media in the system continuously to allow bacterial colonization. Do not replace all existing biological media at once to avoid loss of established bacteria.

Usage recommendations

For best results, integrate Siporax Mini into a multi-stage filtration approach alongside mechanical and chemical media as needed. During tank cycling or after filter maintenance, monitor ammonia and nitrite levels and avoid aggressive cleaning that would remove the biological film. Periodic gentle rinsing in aquarium water is sufficient to remove debris without damaging bacterial colonies.
