Dark substrate for freshwater and saltwater aquariums.

Main Features:
• Ideal stabilization for plant roots: Substrate with a grain size of 0.2-0.6 mm for freshwater and marine aquariums and plant gardens.
• Strong plant growth: Prevents leakage of clay and other waste materials thanks to its fine grains and density.
• Ideal for fish, invertebrates, and plants: Does not release unwanted pollutants into the water. Fine granite sand is gentle on the sensitive whiskers of bottom-dwelling creatures.
• No light reflections - full coloring for plants and fish: Animals that are easily frightened feel more comfortable and display their full natural colors.
