The Indian Almond Tree (Terminalia catappa) provides many gifts for aquarists, including its wonderful bark. Like the leaves, 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 from the trees 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 all beautifully random and imperfect! We try to give you a little variety in each pack... We find this randomness quite charming, and each package will have a few of each type for you to play with.
They're good-sized, and average about 6 inches (15.24cm) long, and about 3/4" (1.9cm) in diameter/width- really good-sized peices- forming a perfect little habitat for ornamental shrimp and small fishes. These are darker, more "rugged-looking", and somewhat "heftier" than our Borneo Catappa Bark Strips. Your Plecos and other catfishes actually will incorporate the bark as part of their diet, so you'll want to replace it over time. And, of course, they're just super cool for using to condition your water, imparting tannins and other beneficial humic substances.
These bark pieces will impart a nice little humic acid "tint" to the water, so if you want to minimize the coloration in your aquarium (really?), it's not a bad idea to boil them for a few minutes, or simply soak them for a few days prior to use. This will also help them become more waterlogged (the darned things love to float!).
They will very, very slowly decompose, and may be replaced as desired.
You can use as many as you'd like, taking into account their ability to color the water and affect pH. Tannin Premium Catappa bark comes 6 pieces to a package, for extra value!
NOTE: Because these are a natural product, rolled by hand, each one will differ in appearance. The photo shown is to provide an idea of what to expect the product to look like.
