JBL BioNitratEX - Nitrate Remover (100 bio balls)

Biological filter material for the removal of nitrate If you don’t get anything to eat you’ll starve to death:Nitrates and phosphates form main nutrients for algae. If one or both nutrients are withdrawn from the water, the algae will stop growing!However, bacteria only break down nitrate under specific conditions: Only when there is no longer any oxygen, but there is a carbon source (a nutrient for bacteria) available do the bacteria remove the oxygen from the nitrate, thus breaking it down.That’s how JBL BioNitratEx works:Bacteria settle on the surface of the JBL BioNitratEx bio balls within about 4 weeks and form a thick biofilm. Beneath the biofilm a low-oxygen zone forms, in which the bacteria start the denitrification process to degrade the algae-promoting nitrate (NO3). The bio balls serve the bacteria as food and the nitrate serves as a supplier of oxygen. That’s why the bio balls become smaller as time goes by (easy to check visually) and disappear completely.
