Alder cones 25g and 50g

Alder cones for aquariums – natural humic substances & water care for fish, shrimp and plants

Alder cones are a proven natural product for biological water treatment in aquariums. They gently release humic substances, tannins, and valuable secondary plant compounds that slightly acidify the water, reduce germs, and create a natural blackwater environment. Cichlids, shrimp, tetras, and sensitive species in particular benefit noticeably from these positive effects.

Whether added directly to the aquarium or boiled as a humic decoction/concentrate – alder cones offer a cost-effective, natural and effective way to stabilize water parameters and promote the well-being of the animals.
