A lightweight, fine substrate featuring black pebbles, perfect for both freshwater and marine aquariums.
Key Features: • Substrate with a 0.8mm grain size suitable for freshwater and marine aquariums as well as terrariums. • Protects delicate mucous membranes: the coarse, rounded natural sand is gentle on sensitive barbels, making it ideal for digging fish such as rays, kuhli loaches, catfish, and more. • Great for fish, invertebrates, and plants: does not release any harmful pollutants into the water. • Application: Layer the substrate over the nutrient substrate (about 6-8cm deep for optimal plant growth). It works well with undergravel heater cables.
