WIO Black Venom gravel
Our Black Venom gravel can be perfectly combined with our Black Venom Boulders or used as a stand-alone substrate. The dark gray, smooth surfaces of these river stones provide soft contrast and texture when combined with plants and other hardscapes and would look particularly good when used as detail around plants such as Anubias. They are also ideal for creating 'flow biotopes'!
Available in 2kg and 5kg bags:
