## Summary description

Biological filter media sera Siporax Professional, 15 mm granules, 10 L volume. Designed to provide a large surface area for beneficial nitrifying and denitrifying bacteria in aquarium and pond filtration systems. Stable ceramic-like grains promote effective biological water purification, reduce ammonia and nitrite, and are suitable for internal and external filters, biofilters and sump systems.

## Long description

sera Siporax Professional 15 mm granules in a 10 L volume are biological filter media designed to support stable and efficient nitrification and denitrification in aquarium and pond filtration systems. The stable, ceramic-like grains provide a high specific surface area where beneficial bacteria can colonize, promoting the breakdown of ammonia and nitrite and contributing to improved water quality. The product is suitable for use in internal and external filters, biofilters and sump systems where long-term biological filtration is required.
Advantages
The porous, durable structure of the 15 mm Siporax Professional granules ensures a consistently large surface area for bacterial colonization, improving biological filtration performance without breaking down into fines. The grains are chemically inert and resistant to water flow and mechanical stress, which supports long service life and stable filtration conditions. Their uniform size and shape promote even water distribution and reduce channeling in filter beds.
Suitable for
Freshwater and marine aquaria requiring biological filtration media
Pond filters where nitrifying and denitrifying bacteria are needed
External canister filters, internal filters and wet/dry biofilters
Sump systems and refugiums that require high-surface-area media
Key specifications
Granule size: approximately 15 mm
Volume: 10 litres
Material: stable, ceramic-like porous granules
Function: biological filtration media for nitrification and denitrification
Compatibility: suitable for use in freshwater and marine systems
How to use
Rinse the Siporax Professional granules briefly with dechlorinated water to remove any dust from packaging before placing them into the filter. Place the media in a filter chamber or basket where even water flow is ensured; avoid packing too tightly to maintain good circulation. For new systems, introduce seeded media or allow several weeks for stable bacterial colonization while monitoring ammonia and nitrite levels. In established systems, replace media gradually if required to preserve beneficial bacterial populations.
Usage recommendations
Monitor water parameters during the initial colonization period, and avoid replacing all media at once to prevent sudden loss of nitrifying bacteria. Clean the granules only by gentle rinsing in aquarium or pond water during maintenance; do not use tap water containing chlorine. Combine Siporax Professional with mechanical prefiltration to reduce clogging and extend service intervals.
