White substrate for aquariums

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 waste material from seeping in
No release of unwanted pollutants into the water. Fine, round-shaped quartz sand is gentle on sensitive barbels
Use: spread substrate on top of the nutrient substrate (approx. 6-8 cm for vigorous plant growth)
Package contents: 1 bag Sansibar White. Not fully suitable for undergravel heating cables
