- Perfect hold for plant roots: substrate with 0.2 - 0.6 mm grain size for freshwater and marine aquariums and terrariums
- Vigorous plant growth: prevents the seeping in of sludge and other waste material with its fine granulation and density
- 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
- Not really suitable for undergravel heating cables
