A light and fine substrate containing black gravel for freshwater and marine aquariums.
Main Features:
• 0.8 mm grain size substrate for freshwater and marine aquariums and water gardens.
• Prevents mucous membrane injuries: coarse natural sand and rounded grains are gentle on sensitive whiskers. Ideal for burrowing fish, such as rays, kuhli loaches, catfish, and others.
• Ideal for fish, invertebrates, and plants: no unwanted pollutants are released into the water.
• Usage: Spread the substrate over a nutrient-rich substrate surface (about 6-8 cm for strong plant growth). Perfectly suitable for under-gravel heating cables.
