ALF Tannin is your go-to solution for creating authentic South American biotopes in your aquarium. This 100ml bottle of concentrated tannin extract is specially formulated to soften water naturally, lower pH levels, and enhance the living conditions of your fish, promoting a habitat much closer to their wild environment. It is ideal for enthusiasts looking to stimulate breeding or provide their fish with the numerous health benefits of tannin-rich water.

Key Benefits

  • Natural Water Conditioning: Our tannin extract naturally softens aquarium water, making it more akin to the waters found in South American rivers.
  • pH Level Management: Tannins naturally increase acidity, helping you adjust and stabilize the pH levels to create an optimal environment for your aquatic species.
  • Encourages Breeding: Mimicking the natural habitat of your fish can induce spawning behaviours, and ALF Tannin is designed to do just that.
  • Health Benefits: Aside from aesthetic improvements, tannins have been linked to health benefits such as improved immunity and reduced fish stress.
  • Easy to Use: The concentrated liquid form makes it simple to dose and mix into your aquarium water.
