Alder cones and alder wood products
Alder wood does not rot under water and is therefore popular as a design element in the aquarium and as additional food for wood-eating Loricariids. The fruits of the alder, alder cones, are very rich in humic substances and have therefore been used almost since the beginning of aquaristics to positively influence the water values.
