JBL’s Manado gravel is a clay-based substrate specifically engineered for use in freshwater and planted aquariums. Manado gravel possesses inert and porous qualities, with its primary advantage lying in its capacity to effectively absorb surplus fertilizers and nutrients from the water column. These absorbed nutrients are retained within the gravel layer, providing an essential resource for the nourishment of plant roots. This advantageous feature not only reduces the potential for undesired algae proliferation but also ensures a greater nutrient supply available for your aquatic plants.
All Manado gravel are available in 5kg & 10kg bags.
