Black Quartz Gravel (5kg)

Black quartz gravel delivers the visual drama of a dark substrate with the practical benefits of a medium-grain gravel. The deep, uniform black colouration is achieved through natural mineral pigmentation rather than artificial coating, ensuring long-term colour stability and complete chemical inertness even after years of submersion.

The dark substrate intensifies the colours of bright freshwater fish and provides an excellent visual contrast for green and red aquatic plants. Its 2–4 mm grain size allows easy gravel vacuuming while still providing firm anchorage for plant roots and decorative rockwork. The polished surface gives the tank a contemporary, professional appearance favoured by photographers and competition aquascapers.
