Alder cones are natural additions to shrimp tanks known for their beneficial properties. These small, cone-shaped structures come from alder trees and are used in aquariums, especially in shrimp tanks, for several reasons. They release tannins into the water, which create a natural environment similar to the shrimps’ native habitats.

The tannins have a mild antibacterial and antifungal effect, promoting a healthier environment for shrimp by potentially preventing diseases and supporting their overall well-being. Additionally, alder cones can slightly lower the pH of the water, making it more acidic, which many shrimp species prefer.

Their gradual decomposition also serves as a supplementary food source for shrimp, as microorganisms and biofilm grow on the cones, providing a grazing area for the shrimp to forage.

When using alder cones in a shrimp tank, it’s important to monitor the water parameters to ensure they align with the specific needs of the shrimp species being kept. Generally, these cones are a popular natural addition among shrimp enthusiasts for fostering a more natural and conducive environment for their aquatic pets.
