Dennerle Deponit NutriBalls Root Fertilizer DE-DB

Strong, healthy plants begin with strong, healthy roots. Use Deponit NutriBalls for targeted fertilization of the roots. This product is a good starter aid and can also be used for complementary fertilization of all aquatic plants that take in their nutrients predominately via their roots.

NutriBalls are easy to use: just push 1-4 balls, depending on the plant size, into the substrate near the roots.
