Sera Siporax Professional Biological Filter Media – High Capacity Aquarium Media 1000ml
Description
Maximise your aquarium’s biological filtration with Sera Siporax Professional — a premium filter media engineered from sintered glass to provide exceptional surface area and promote efficient breakdown of ammonia, nitrite and nitrate.
Whether you’re running a freshwater planted tank, a marine reef system or a large pond, Siporax is suitable across setups and filter types — internal, external or trickle. Its interconnected pore structure supports beneficial bacteria by ensuring optimal water flow and self-cleaning of the media for long service life.
Key Features:
-
Sintered glass construction with advanced pore geometry for maximum bacterial colonisation.
-
Immediate biological activity and long filtration cycles before media replacement.
-
Suitable for fresh, saltwater and pond use, regardless of filter type.
-
Available in multiple volumes to fit systems from ~100 L aquariums up to large ponds of thousands of litres.
-
Ideal choice for hobbyists seeking stable water parameters and low maintenance.
Usage Tips:
-
Rinse the media lightly in aquarium water (not tap water) before placement to remove dust.
-
Place in a section of the filter with good water flow for highest efficiency.
-
Combine with good mechanical filtration upstream (e.g., filter wool/sponges) to reduce detritus load. Rarely needs full replacement — clean gently when flow decreases significantly.
