Description: Alder cones are derived from the Black Alder Tree and are used widely in the aquarium hobby alongside other 'botanicals' such as Indian Almond Leaves. The tannins and humins released from alder cones are what makes them so beneficial.
Directions: As a rule of thumb use 1 Alder Cone per 20l of aquarium water. If you do not want to stain your aquarium water with tannins, the alder cones can be soaked prior to adding to your tank. Observe the water chemistry and colour and add more Alder Cones as desired.
