Dried Jack Leaves are a fantastic additon to the tropical freshwater aquarium. As the leaves breakdown, Tannin Acids are released which aid as a natural antibacterial agent and help to lover the pH of an aquarium. For the Biotope style keeper, such leaves are really important to not only finish a natural look off, but also to aid in the wellbeing of their fish and invertebrates. 
 
In comparison to some of our other leaves, Jack Leaves break down a little slower. Perfect for the Aesthetic appeal, but adding less Tannin Acid into the water column.
