Dennerle Kristall Dark Brown Quartz Gravel is a high-quality aquarium gravel for freshwater aquariums. Its rich, dark brown hue creates a warm and natural look in the aquarium. Especially when combined with roots, rocks, and green aquatic plants, it creates a harmonious overall appearance. Fish and shrimp stand out beautifully against the darker substrate. The quartz gravel is water-neutral, CO2-resistant, and does not harden the aquarium water. This makes it suitable for planted aquariums with CO2 fertilization and does not affect water parameters. The fine grain size of 1-2 mm is plant-friendly, provides a good colonization surface for beneficial bacteria, and reduces larger accumulations of debris in the substrate.
Thanks to its rounded edges, Dennerle Kristall Dark Brown Quartz Gravel is also suitable for bottom-dwelling fish. The gravel is free of harmful substances, lightfast, and permanently colored with iron oxide to remain water-neutral. According to the manufacturer, the quartz gravel does not need to be pre-washed before use.
