Fritz Nature Box

The benefits of tannins in aquariums have been widely studied and documented. We can rely on them as an anti-fungal and anti-bacterial agent, preventing some infections of fish and fish eggs. Algae growth can be slowed or eliminated, and pest snails and crustacean populations are controlled. Species that prefer low pH and soft water will thrive, showing vibrant colorations and increased spawning behavior.

Catappa leaves are commonly used in the hobby to create blackwater biotope aquariums, as shelter for fish, shrimp, and fry, as well as for their healing properties.

Fritz Nature Box contains Indian Almond leaves, sliced Catappa almond bark, and Casuarina cones, each giving a unique application of tannins, humic acid, and habitat. They each provide tannins, lower pH, have anti-fungal and anti-bacterial properties, control pest snail populations, and enhance coloration and increase spawning behavior.

Robust almond leaves provide shade, sites for bubble nests, spawning sites and hiding places for fry, and food sources for many ornamental shrimp species. Catappa bark and Casuarina cones are a long lasting source of tannins that offer the same water conditioning benefits as almond leaves.
