Benefits of alder cones for aquaristics

What are alder cones?

Alder cones (in English "Alder cones", which is also a common term for commercially sold cones, although you can easily collect them yourself for free) are small fruits of the black alder (Alnus glutinosa). When added to an aquarium, they release beneficial compounds such as tannins and humic acids, which positively affect the chemical composition and health of aquatic organisms. The natural properties of alder cones have a multifaceted benefit for aquatic organisms and water quality. Therefore, they have become a popular natural additive in aquariums, especially for shrimp and fish enthusiasts.

Benefits of using alder cones for aquarium fish and shrimp:

1. Natural way to condition water in the aquarium

Alder cones release tannins and humic substances into the water, which:

- lower the pH, thereby helping to create a more acidic environment suitable for species from blackwater aquatic biotopes
- suppress the growth of harmful bacteria and fungi, thus reducing the risk of infections
- provide a natural appearance to the water in the aquarium by coloring it a light amber hue, which is the color of natural biotopes

2. Health benefits for shrimp and fish

The compounds released by alder cones strengthen the immune system of shrimp and fish, support successful molting of shrimp, and improve their coloration and overall vitality.

3. Advantages of alder cones for breeding

Alder cones help create optimal conditions for the development of eggs and the survival of fry, and reduce the likelihood of fungal infections on the eggs.
