Alder Cones -15- for Aquariums – Blackwater Botanical for Shrimp, Bettas & Breeding Tanks

Alder cones are a natural way to enhance the health and beauty of your aquarium. Rich in tannins and humic substances, they help lower pH, reduce harmful bacteria, and create soft, blackwater conditions favored by shrimp, bettas, and other tropical fish. These cones also help prevent fungal infections, especially on fish eggs, making them ideal for breeding tanks. As they slowly release beneficial compounds, they also add a warm tint to the water and encourage natural behavior in fish and invertebrates. Use 1 cones per 10 gallon and replace them every 3–4 weeks or when fully broken down. Each cone is naturally sourced, sun-dried, and free from pesticides or chemicals. Whether you’re creating a biotope or just want healthier water, alder cones are an easy, effective, and natural addition to your tank.
