Sera Siporax Nitrat-Minus Professional Filter Media

What is Sera Siporax Nitrat-Minus Professional Filter Media?

Sera Siporax Nitrat-Minus Professional Filter Media is a high-performance filter medium for biological nitrate breakdown with parallel breakdown of nitrite and ammonium. Denitrification is optimally enhanced and maximised by the bio polymer sphere matching the Siporax ring. The degradable bio polymer serves as a carbon source for the bacteria that break down nitrate.

Key Features:

• High performing filter media
• Biologically breaks down nitrate as well as nitrite and ammonium
• Maximum biological filtration in an aquarium
• Increases the holding time of a filter
• Breaks down pollutants easily for healthy water
• Optimises the water flow in your aquarium
• Almost maintenance-free
• Very long-lived filter media
• Reduces the number of water changes needed
• Excellent for use in bigger or densely stocked community or cichlid tanks

What are the benefits of Sera Siporax Nitrat-Minus Professional Filter Media?

The bio polymer sphere not only maximises the biological filter performance of the unique sintered glass tube, but at the same time also increases the holding time of the filter in two ways. Besides pollutant breakdown, the special construction of the sphere optimises the water flow and thus improves substance transport into the inner Siporax ring. Sera Siporax Nitrate-Minus Professional therefore is an almost maintenance free and long-lived filter medium. The number of water changes can also be reduced. Water parameters can be improved by Siporax Nitrate-Minus Professional especially in bigger and/or densely stocked community or cichlid tanks. The bio polymer spheres are broken down by bacteria over time, and dissolve. They can simply be replaced by renewing the carbon source.

Please note: In dedicated plant tanks or aquariums with dense planting and corresponding nitrogen requirements, this filter medium can lead to additional NPK fertilisation being necessary.
