A dark substrate forms a much stronger contrast to green plants and fish colours than a brown or a light substrate. That’s why JBL has added a darker colour to the natural substrate Manado range, already tried and tested by plant enthusiasts.
JBL Manado Dark, with its porous structure, promotes the root growth of aquarium plants and, just like a battery, can store excess nutrients and release them again when they are needed. The iron bound in Manado Dark is accessible to the plant roots and promotes growth in even the most demanding of plants. The substrate works with the aquarium filter and provides crystal clear water. JBL Manado Dark is available in four pack sizes (1.5, 3, 5 and 10 l).
