Fritz Casuarina Cones gives a unique application of tannins, humic acid, and habitat. Casuarina cones provide tannins, lower pH, have anti-fungal and anti-bacterial properties, enhance coloration and increase spawning behavior. The tannins released from these pieces create a more natural environment for Bettas, shrimp and other fish. Casuraina cones contain humic acids and tannins which are known to have antibacterial properties, naturally lower pH and create blackwater conditions in the aquarium. Fritz Casuarina Cones are suitable for all soft-water fish including betta, discus, tetras, angelfish, and killifish. Directions & Dosage Recommended application: Add 1-2 small cones per gallon. Add directly to aquarium or pre-soak for faster sinking. Replace when tissue is decomposed or consumed.
