sera siporax Nitrat-minus Professional is an effective filter material for the biological breakdown of nitrates, nitrites, and ammonium. Denitrification is enhanced thanks to the biopolymer spheres, which are designed to fit the siporax rings.

The biopolymer spheres increase the biological efficiency of the filter made from porous glass, optimizing water flow and contributing to the breakdown of harmful substances. siporax Nitrat-minus Professional requires minimal maintenance and has a long lifespan, reducing the frequency of water changes, especially in larger or crowded aquariums.

It can be combined with other siporax products, such as siporax Professional, mini Professional, and pond Professional, enhancing the breakdown of harmful substances through carbon supply.

The renewal of the carbon source is simply achieved by replacing the polymer spheres as they decompose over time.

• Dosage: 1 sphere for every 15 liters of aquarium water
• Note: In heavily planted aquariums, additional NPK fertilization may be required.
