Guava leaves are known for their antibacterial properties and are also a good natural food source for shrimp! When the Guava leaves are placed in the aquarium, a sticky biofilm will form on the leaves over time. This biofilm provides a food supply that is available 24/7. The leaves of the Guava plant are tougher and decay less quickly than Catappa leaves. It is therefore less often necessary to replace the guava leaves.
We recommend using the guava leaves to prevent vibriosis outbreaks in your aquarium. You will notice that the natural tannins in these leaves slightly lower the pH of the aquarium water. In addition, the tannins also help with the impoverishment (shedding) of shrimp, ensure that they retain their beautiful colour and stimulate breeding.
Boil the leaves for 10 to 15 minutes, let them cool and place them in the aquarium. The leaves then sink to the bottom fairly quickly. Guava leaves have an unlimited shelf life (when dried).
• Use 1x leaf per 20L, replace when dissolved/decayed or eaten.
