Black Venom Gravel from the WIOdecor Gravels series by the manufacturer WIO is a natural gravel with a dark grey colour. Wet, it appears much darker and has colour accents ranging from anthracite to black.
The dark grey, smooth surfaces of these river pebbles contrast harmoniously with plants and hardscape. The grain sizes of Black Venom Gravel can be optimally combined.



  • Anthracite to black look
  • Does harden the water
  • Available grain sizes 8 - 20, 8 - 40 & 20 - 40 mm
  • Natural look
  • Available in 2 kg containers


All WIOdecor gravel types are pre-washed. Nevertheless, the manufacturer recommends briefly rinsing the gravel with cold water before use to wash off any abrasion caused by transport. This also prevents grains of sand from floating up when the aquarium is filled.
