Crystal Quartz Slate Gray Gravel for Freshwater Aquariums

The Dennerle Quartz Gravel is a perfect blend of beauty and functionality. It offers exceptional biological performance, isn't affected by CO2 or light, and doesn't harden the water. The iron oxide coloring is long-lasting, ensuring that it retains its color for years. With a grain size of 1-2mm, it's perfect for bottom-dwelling fish and helps prevent dirt buildup in the gaps. It's also suitable for plants with delicate roots. The rounded grains minimize the risk of injury to aquarium animals, while the small gaps provide an ideal settlement area for crucial bacteria. The quartz gravel is water-neutral and guaranteed free of pollutants, ensuring a safe and healthy environment.
