Experience an optimal aquatic environment with sera alder cones. Ideal for lowering the pH value in a natural way, these premium cones prevent fungal infections and spawn fungus in a natural way, all while supporting natural behavior and readiness to spawn. Suitable for preparing black water, these cones recreate the natural living conditions, allowing for comfortable and appropriate care. Simply add 1 cone per 10 liters of aquarium water, or up to 1 cone per 1 liter for disease treatments. For best results, monitor the pH value as needed.
