What are sea almond leaves?

Sea almond leaves are also known as the leaves of the Terminalia Catappa.

The Terminalia Catappa tree is native to the tropical coastal regions of East Africa and Asia. The humic acids of the leaves of this leaf species have a strong antibacterial effect and are therefore particularly suitable for use in aquaria. They improve water quality and have a preventive and healing effect on fish infections.
It is not without reason that they are the secret of success of Southeast Asian fish and shrimp breeders.

Why do they help against fish diseases?

The sea almond leaves contain a variety of interesting ingredients. They contain several flavonoids such as quercetin, a number of tannins such as punicalin and a number of saponins and phytosterols.

These substances are a natural remedy for many fish diseases.

The leaves decompose insidiously as soon as they are integrated into an aquarium. This process releases tannins that lower the pH value of the water. These have antimycotic and antibacterial properties. At the same time, there is scattered evidence and theories that the substances reduce the toxicity of heavy metals in the aquarium and bind them. Furthermore, the tannins give the water a brownish colour, which ideally mimics the natural habitat of many fish species.

Notes on use


Store your sea almond leaves in a dry place at room temperature! Dry leaves can easily be stored for six months in an adequate environment.
It is recommended to use a waterproof container that prevents air and light from penetrating. Remove activated carbon and synthetic filter media from the aquarium!
Do not use mouldy leaves!


The following dosages refer to leaves from 15 to 25 cm. Using two leaves per 50 litres of water is a good rule of thumb. Growers normally use one leaf in breeding tanks with a volume of 20 litres.

Period of use

If you do not anchor the leaves with a stone, experience shows that they swim for 2-3 days before they sink. Sinking is natural and does not mean that you have to change the leaves. They usually disintegrate after a month or two, depending on how actively your fish tries to destroy them. Aquarists who don't like the sight of torn leaves usually change them every 2-3 weeks. However, this is for purely aesthetic reasons. Normally the leaves are not changed more often than every two months.
