Alder Cones – Natural Tannin Booster for Aquariums

Enhance water quality and boost shrimp health with Alder Cones. A must-have for blackwater aquariums and breeding tanks. Fast shipping from our Coburg store.

Looking to naturally improve your aquarium's water quality while keeping your shrimp and fish healthy?
Alder Cones are a powerful, all-natural addition to any freshwater setup — especially shrimp tanks, betta tanks, and blackwater aquariums.

✅ Releases beneficial tannins to lower pH and soften water
✅ Antibacterial & antifungal properties – helps prevent infections
✅ Stimulates breeding in shrimp and soft-water fish
✅ Ideal for shrimp, bettas, tetras, corydoras, Apistogrammas, rams and more species of fish that live in low pH (Black water environment)
✅ Creates a natural-looking, bioactive aquascape

Each cone slowly releases humic acids and tannins, replicating the leaf-litter conditions of tropical streams. This not only supports fish health but also encourages vibrant colours and natural behaviour.
