NATURAL WHITE QUARTZ GRAVEL 1–2mm – Fine Substrate for Freshwater Aquariums, 5 kg
Dennerle’s Natural White Quartz Gravel is a refined, crystal-clear substrate designed to combine beauty, functionality, and safety in freshwater aquariums. Made from high-purity natural quartz, this fine gravel is completely free of harmful substances and does not alter water parameters. Its bright, natural white appearance remains stable over time, making it a long-lasting and visually appealing base for any aquascape.
With a grain size of 1–2 mm and rounded edges, this gravel is especially suitable for bottom-dwelling fish and plants with delicate roots. The smooth structure helps prevent injuries to sensitive species and reduces the accumulation of debris, simplifying substrate maintenance. Resistant to both CO₂ and light exposure, the gravel retains its color and properties even after repeated use.
Colored with iron oxide, the gravel is fully water-neutral and safe for all aquatic organisms. The small gaps between the grains provide optimal surface area for beneficial bacteria to settle, supporting biological filtration and contributing to a healthy nitrogen cycle within the tank.
