Naturally Fermented for Enhanced Tannin Release

Premium fermented Catappa leaves (Terminalia catappa) carefully selected, naturally aged, and fermented to provide a richer source of tannins and humic substances for freshwater aquariums.

Ideal for betta fish, shrimp tanks, blackwater aquariums, discus, apistogramma, rasboras, tetras, and other soft-water species.

The fermentation process helps accelerate tannin release while maintaining the natural benefits sought by aquarium hobbyists. Catappa leaves are widely used to create a more natural environment, encourage biofilm growth, and support blackwater conditions.
