The JBL Manado Dark substrate is suitable for digging fish and has nutrient buffer with high iron content. The substrate is capable of storing excess nutrients, to release them again when needed, while 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.
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 round-shaped. 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 luxuriant plant growth even for very demanding plants.
Rinse briefly with lukewarm tap water before use to remove any abrasion rubbed off during transport.
The right amount of substrate: length (cm) x width (cm) : 200 = litres substrate with 5 cm thickness.
