sera siporax Nitrat-minus Professional

Biological filter medium for nitrate removal in aquariums

sera siporax Nitrat-minus Professional is a high-performance filter medium for biological nitrate reduction with parallel reduction of nitrite and ammonium. The biopolymer ball, which is tailored to the siporax ring, optimally increases and maximises denitrification. The degradable biopolymer serves as a carbon source for the nitrate-degrading bacteria.

The biopolymer ball not only maximises the biological filter performance of the unique sintered glass tube, but also increases the service life of the filter in two ways. In addition to breaking down harmful substances, the special design of the ball optimises water flow and thus improves the transport of substances into the inner siporax ring. This makes sera siporax Nitrate-minus Professional a virtually maintenance-free and, above all, long-lasting filter medium. The number of water changes can also be reduced. siporax Nitrate-minus Professional can improve water values, especially in larger and/or well-stocked community and cichlid tanks.

sera siporax Nitrate-minus Professional can be combined with existing siporax products such as siporax Professional, siporax mini Professional and siporax pond Professional, and also increases pollutant reduction there by adding carbon.

The biopolymer balls are decomposed by bacteria over time and dissolve. They can be easily replaced to renew the carbon source.

Note: In pure plant tanks or aquariums with heavy planting and corresponding nitrogen requirements, this filter medium may require additional NPK fertilisation (e.g. with sera flore 4 plant).
