## Summary description

Sera Siporax Professional is a biological filter media with 15 mm particle size, supplied as a 14.5 kg pack. Designed for aquarium and pond filtration, it provides surface area for beneficial bacteria to colonize and support biological nitrification.

## Long description

Sera Siporax Professional 15 mm is a biological filter media supplied in a 14.5 kg pack, designed to support stable biological filtration in aquariums and ponds. The spherical granules provide a porous surface that encourages colonization by nitrifying bacteria, improving ammonia and nitrite conversion. The product is suitable for use in canister filters, trickle filters and other mechanical or biological filter systems that require high surface area for bacteria and reliable water quality maintenance.
Advantages
Sera Siporax Professional offers a high internal surface area within compact 15 mm granules, enabling efficient bacterial colonization while maintaining good water flow and low risk of clogging. The durable, chemically inert material resists degradation and does not affect water chemistry. Supplied in a large 14.5 kg quantity, it is practical for larger aquaria, ponds or for replacing media in multi-chamber filtration systems.
Suitable for
Freshwater and marine aquariums with biological or combined mechanical/biological filtration
Pond filtration systems requiring reliable nitrification
Canister filters, trickle filters and external biological reactors
Systems needing long-lasting, low-maintenance filter media for ammonia and nitrite control
Key specifications
Particle diameter: approximately 15 mm
Packaging weight: 14.5 kg
High internal porosity for bacterial colonization
Material: chemically inert, durable ceramic-like media
Designed for both freshwater and marine applications
How to use
Rinse the media briefly with dechlorinated water to remove dust before placing it in the filter. Arrange the Siporax granules so that water flows evenly through the media bed; avoid compacting the particles to preserve flow and access for bacteria. For first-time setups, introduce in combination with established biological media if possible to accelerate colonization, and allow several weeks for a mature bacterial community to develop. Replace only part of the media at a time during maintenance to preserve beneficial bacteria.
Usage recommendations
Monitor ammonia, nitrite and nitrate levels regularly after installing the media, especially during the initial colonization period. Use the media as part of a balanced filtration setup that includes mechanical pre-filtration to reduce solids loading and extend media lifetime.
