JBL Manado Gravel Dark

• 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
