  • Features a high-biomass, high-performance nitrifying bacteria consortium
  • Specifically to eliminate ammonia and nitrites in aquatic ecosystems
  • Actively oxidizes ammonia and nitrites, neutralizing their toxic effect on the aquatic life
  • Helps maintain a balanced aquatic ecosystem
  • Contributes positively to the health of aquatic animals and plant life
  • Reduces the risk of sickness and death among fish and plants

    The intake of nitrifying bacteria is justified because of the intense biological activity, the decomposition of plant residues and the accumulation of droppings and uneaten fish food and ammonia which tends to accumulate rapidly in closed or semi-open aquatic environments.

    It remains imperative to prevent this accumulation because ammonia is a chemical compound extremely toxic to any aquatic environment.

    The nitrifying bacteria found in Bacterius® N have the ability to rapidly oxidize ammonia and nitrites to a non-toxic nitrogen compound. Using Bacterius® N in aquatic environments is beneficial and provides an effective solution for regulating nitrogen compounds.

    Aucun résultat

    Je suis vraiment dessus car après trois mois d’utilisation je n’ai absolument pas de résultat. Et j’ai suivi les conseils du représentant à qui j’ai parlé, les quantités et au combien de temps…
    J’ai utilisé Baterius N et C j’ai toujours des algues visqueuses et de la vase.
    Pour le prix, c’est vraiment du gaspillage d’argent car c’est vraiment coûteux.

    Bonjour Ysabelle,
    Merci pour votre avis concernant le produit Bacterius N. Un étang étant un milieu vivant, les résultats des produits de traitement d'eau par bactéries Bacterius peuvent varier d'un étang à l'autre. Nous remarquons tout de même que des résultats positifs sont observés entre quelques semaines à 1 été complet. Selon notre système, 6 semaines se sont écoulés entre l'expédition de votre commande et votre avis, ce délai étant relativement court pour voir un effet important, nous recommandons donc de poursuivre les traitements.
    Pour toute question n'hésitez pas à nous contacter, nous serons ravis de vous aider dans votre démarche pour un étang en santé! Au plaisir!

    Great Product, shipping is expensive!

    I think the Bacterius N, Nitrifying Bacteria product is excellent and works really well. Thank you for making it! The only issue I have is the expensive shipping costs which cost me twice the listed item price of the product, going from their Quebec warehouse to a major city in Alberta. I suggest that considers being a seller on Amazon to reduce the shipping costs to the consumers. I hope that can work for you and your customers.

    Hi David,
    First we would like to thank you for your review on the Bacterius N products. We are very happy that you are satisfied with this product!
    We also wanted to let you know that we just launched our Bacterius store on a few weeks ago so you can purchase Bacterius products through Amazon. We are starting with a limited amount of skus which does not include the Bacterius N unfortunately but we are thinking to expand the range eventually. Keep looking at our store to see if the Bacterius N becomes available on
