Overview

"Biological filtermaterial for the removal of nitrates
• Removes the main nutrient of algae, nitrate, off the water.
• Operates exclusively through nitrate-eliminating bacteria, without the use of chemical additives or exchange products.
• Bacteria need no extra feeding, as substrate includes feed.
• Also suitable for use in saltwater in combination with the active carbon JBL Carbomec ultra as after-filter.
Product description
Controlling algae growth and improving the conditions of aquarium life by nitrate breakdown – made easy.
1. How does nitrate get into the aquarium?

The breakdown or mineralising process of all organic matter in the aquarium (feed and plant residues, fish excrements) happens through the stages protein > ammonium > nitrite > nitrate. Certain bacteria, which prefer to settle in the filter and on the aquarium floor, are responsible for this process. Nitrate in relatively high concentrations is not harmful to fish. The bacterial conversion of the waste matter in the aquarium into nitrate is, as it were, the life insurance for the fish because toxic intermediate products cannot enrich in well tuned filters.

But since a high content of nitrate promotes the growth of unwanted algae, the nitrate content in the aquarium water should not be allowed to exceed about 50 mg per litre. Regular partial changes of the aquarium water used to be the most common method for reducing the nitrate content. Ion exchanger resins and biological nitrate filters are also widely used.
2. What is biological denitrification?

Biological denitrification is the reduction of nitrate into gaseous nitrogen through bacteria. This is a phenomenon which has been well-known in agriculture for a long time and which results in an undesirable nitrogen depletion in the soil. Certain bacteria are capable of using the oxygen bound in the nitrate molecules for breathing, and in the process reducing the nitrate into gaseous nitrogen which eventually escapes into the air. This process is known as denitrification. It can also be used to remove nitrate from the aquarium."
