About Fritz Dark Water

Fritz Dark Water Almond Leaf Extract is a natural water conditioner containing concentrated tannis from the leaves of the Terminalia catappa tree, also known as as Indian Almond Leaves. These tannins create a more natural environment for Bettas, shrimp and other fish. Almond leaves contain humic acids and tannins which are known to have antibacterial properties, naturally lower pH and create blackwater conditions in the aquarium. Fritz Dark Water Almond Leaf Extract is suitable for all soft-water fish including betta, discus, tetras, angelfish, and killifish.

Directions & Dosage

To increase tannins by 1 ppm: ​​​​​​Add 5 mL (1 tsp) per One U.S. Gallon (3.8 L) or 6 drops per cup (236 mL). Add to new water during water changes. Avoid overdosing.
