Wio Black Venom Nano Rocks – 2kg

A rich and bold black colouration, combined with star, clean lines and textured surfaces make these stones into an essential part of the Aquascapers pallet. When used alongside bright green plants, especially those with soft textures such as Eleocharis, these rocks bring impact and drama to the display.

*This rock may raise pH and hardness slightly.
*Standard regular water changes are enough to keep the hardness under control
