Create a more natural and healthy aquatic environment with Premium Alder Cones, a popular botanical used by aquarists worldwide to enhance water quality and recreate natural blackwater habitats. Rich in beneficial tannins and humic substances, Alder Cones help support shrimp, bettas, corydoras, rasboras, and other tropical fish by providing a more natural environment similar to their native waters. As Alder Cones slowly break down in the aquarium, they release tannins that gently tint the water a natural tea color while providing antibacterial and antifungal properties that can benefit fish, shrimp, and fry. Perfect for shrimp tanks, betta aquariums, planted tanks, and blackwater biotopes, Alder Cones are a simple and natural way to improve aquarium conditions.
