Substrate with 0.8 mm grain size for freshwater and marine aquariums and terrariums
Prevents injuries of the mucous membrane: coarse-grained, spherical-formed natural sand is delicate on sensitive barbels. Ideal for digging fish, such as rays, kuhli loarch, catfish, and so on.
Ideal for fish, invertebrates and plants: no unwanted pollutants released into the water.
Use: Unfold substrate on best of the nutrient substrate (approx. 6-8 cm for full of life plant enlargement). Smartly suited to undergravel heater cables
