Indian Catappa Bark


The Indian Almond Tree (Terminalia catappa) provides many gifts for aquarists, including its wonderful bark. Catappa bark offers a rich source of tannins, humic acids, and other substances which  are thought to provide antibacterial and antifungal properties and other health benefits for aquarium inhabitants.

Tannin Indian Catappa Bark is harvested in a sustainable manner from a small village in India just for us. They are carefully cleaned, dried, and some are rolled  into attractive little "logs", with tons of character! Others retain their natural form; slightly curved and "open." 

They're good-sized, too, and average about 6 inches (15.24cm) long, and about 3/4" (1.9cm) in diameter/width. They're great for conditioning your water, imparting tannins and other beneficial humic substances.

PREPARATION: We think the best way his to boil them for about 20-30 minutes before adding to your aquarium. Alternatively, you could simply soak them in water for a few days to saturate them.


ORIGIN: Marthandam, Tamil Nadu, India
