Walnut leaves are a forerunner of sea almond leaves in aquaristics and are highly valued, particularly for their broad spectrum of action.

The decomposing leaves are primarily consumed by invertebrates such as dwarf shrimp, dwarf crabs, and snails, but they are also consumed by wood-eating loricariid catfish, making them ideal for long-term feeding.

Boil all botanicals for 60 minutes to remove germs, dirt, and debris. Allow your botanicals to soak in dechlorinated, ro or aquarium water overnight before placing them in the aquarium.

You can use the soaking water as dark extract since it contains a descent amount of beneficial tanins.
