JBL TerraBasis substrate, 20L

JBL TerraBasis substrate is a natural stone bed designed for freshwater aquariums. Its appearance mimics the rainforest floor, helping to create a natural habitat for aquarium fish. Crucially, the substrate does not affect the chemical properties or hardness of the water. The fine maximum grain size of up to 3mm is safe even for bottom-dwelling fish. The 20L pack provides enough substrate to set up or update medium-sized tanks.
