A stable and functional substrate is essential for the well-being of the fish and plants in your aquarium. Aquarium Gravel Lava Substrate, made of large lava granules (Ø 2 – 8 mm), provides exactly this basis. Its porous structure promotes water circulation in the substrate, which not only supports the ecological balance, but also creates additional surface area for the colonization of beneficial bacteria. These bacteria contribute to the biological filtration of the aquarium and improve water quality.
The substrate is particularly stable and is ideal as a base for heavy stone or wooden structures. The loose structure of the material also ensures even distribution of nutrients and promotes the healthy growth of aquarium plants.
Aquarium Gravel Lava Substrate is neutral in water and has no influence on water parameters, making it a safe choice for freshwater and saltwater aquariums. Its natural dark gray color blends harmoniously into any aquarium landscape and combines ideally with various decorative elements such as stones or wood.
