Perfect hold for plant roots: substrate with 0.2 - 0.6 mm grain size for freshwater and marine aquariums and terrariums
Ideal for aquarium care: its fine granulation and density prevents mulm and other waste material from seeping in
Ideal for fish, invertebrates and plants: no release of unwanted pollutants into the water. Fine granite sand is gentle on the sensitive barbels of the bottom-dwellers
No light reflections ? full colouring of plants and fish: easily scared animals feel more comfortable and show their full, natural colouring
