JBL Manado Dark

JBL Manado Dark is a natural substrate for freshwater aquariums.

• Perfect for the plant care in freshwater aquariums. Its porous structure promotes the growth of roots. Suitable for digging fish
• Nutrient buffer with high iron content. Is capable of storing excess nutrients, to release them again when needed. The high iron content is absorbed by plant roots
• Activates the soil flora by motivating the quick and effective colonisation of beneficial ground bacteria. This inhibits the growth of unwanted algae, reducing the work-load on the filter and ensuring crystal-clear water
• Accentuates the beauty of the fish: its dark-brown tone highlights their colours and combines with the green and red tones of the aquatic plants to create a harmonious appearance
• Ready-to-use substrate which needs to be rinsed once in tap water before use. Available in various packaging sizes

Successful plant care:
The natural substrate activates the soil flora and is ideal for plant care. The nutrient buffer with battery effect (releases nutrients until it is depleted and can be reloaded through new fertilisation) is water-neutral and rounded. As a result it is ideally suited for digging fish species, such as cat fish and loaches.

Combination with long-term nutrient substrate:
A supplement with JBL ProFlora AquaBasis plus as long-term nutrient substrate with JBL Manado Dark as a covering layer guarantees vigorous and healthy plant growth even for very demanding plants.

Use:
Rinse briefly with lukewarm tap water before use to remove any abrasion rubbed off during transport.

McMerwe’s Review: This is the best inert substrate available for plants in our opinion. It’s very expensive compared to other inert substrates. It contains no nutrients out of the bag, but we believe it can absorb some nutrients to a degree. It is very light in weight and plant roots can easily be developed without being pressured by the weight of the granules. Roots can easily move the granules out of the way. The colour also looks natural. It requires a thorough rinse. Some granules float, but they will eventually sink as they get waterlogged. (Rating: 5/5)
