Grey, fine substrate for freshwater and saltwater aquariums.

Key Features:
• Fine, uncoloured sandy soil: substrate for fresh and saltwater aquariums and aqua-terrariums.
• Vigorous plant growth: prevents the seeping in of sludge and other waste material with its fine granulation and density.
• Prevents injuries of the mucous membrane: fine, round-shaped natural sand is gentle on sensitive barbels. Ideal for grubbing fish, such as armoured catfish and loaches.
• Ideal for fish, invertebrates and plants: no unwanted pollutants released into the water.
