The Black Venom Nano Rocks from the WIOdecor Nano Rocks series by the manufacturer WIO are deep black, heavily textured stones. The clear lines and surfaces make these stones effective design options in the aquascape. Together with green plants, especially those with soft shapes such as needle cress, these stones bring a particularly attractive look to the aquarium.


  • Deep black colouring
  • Interestingly textured surfaces
  • May slightly increase the pH value and the KH
  • This rock may raise pH and hardness slightly
  • Available in 2 kg containers


These stone sets are unhalndled natural products. It is recommended to clean and rinse the stone decoration under running water before using it in the aquarium. This removes the finest stagnant particles, which can otherwise cause cloudiness when a new aquarium is set up. Slight residues of moss or lichen cannot be completely ruled out.
