The XXL substrate Dark Mountain by Greenscaping is made of pure volcanic rock, mined and manufactured in Germany.

This rock, originated in the German Eifel, is characterised by its porous structure which enhances the circulation of water around the substrate. This effect prevents the plant roots from rotting. At the same time, the substrate provides optimal assistance for the set up of hardscape due to its variously sized grains that promote wedging and thus strong hold.

Dark Mountain Substrate XXL is washed under high pressure several times so that no cloudiness or dust limits the joy of a freshly set up aquarium layout.
It is best suited for bases of 30 cm height and above. For all smaller substructures, Dark Mountain Substrate is recommended.


  • Stable substrate for perfect hardscapes
  • Porous structure promotes plant growth
  • Air circulation around the substrate is supported
  • Already washed rock, no dusting and clouding
  • All-natural product, mixture of different types of stone.
  • Especially for high substructures


Greenscaping provides this calculation formula for the amount of substrate you need: length (cm) aquarium x width (cm) aquarium x height (cm) substrate / 800 = kg Dark Mountain Substrate
The average desired height is given here as the substrate height.
