Catappa Tea Bags – 12 pk
Tannins, found in substances like Catappa leaves, offer several benefits in aquariums, making them a popular choice among hobbyists. They have plenty of advantages! Tannins help to prevent fungal and bacterial infections in fish and their eggs, reducing the risk of disease in the aquarium. By influencing water chemistry, tannins can slow down or even eliminate algae growth, keeping your aquarium cleaner and reducing maintenance. Tannins can also help manage populations of pest snails and crustaceans, which can otherwise become problematic in aquariums. Fish species that thrive in low pH and soft water conditions will benefit from tannins, often showing more vibrant colors and increased spawning behaviors, and enjoying the shade provided by the leaves.

Used Catappa tea bags in my community tank with neon tetras and dwarf gouramis. The water turned slightly yellow, which I liked. My fish seemed more active and the algae growth dropped noticeably after a week. Easy to use, just add one bag per week.
Colin Duncan –
Good for soft water tanks. My fish have shown better coloration since using the tea bags. A little algae reduction, but not complete. Works well with snail populations too.
Christopher Davies –
Added one tea bag weekly to my 50-gallon tank. Noticed fewer fungal infections in fry and less algae. The water color change was subtle but consistent. Very satisfied with the results.
