NATURAL GRAVEL RIO BRANCO 0.1–0.2 mm – Fine Dark Gray Natural Aquarium Gravel, 2.5 kg Pack
Natural Gravel Rio Branco 0.1–0.2 mm, in a 2.5 kg package, is a premium-quality fine dark gray natural sand, ideal for creating clean, high-contrast aquascapes inspired by the Rio Branco riverbed. Its ultrafine grain size is perfect for compact substrates, accent zones, and minimalist aquascaping with smooth textures and natural flow.
The 0.1–0.2 mm grain size creates a smooth, consistent base that highlights the bright greens of aquatic plants and contrasts beautifully with décor elements like Black Lava, Mini Landscape, Grey Slate, and Lake Mountains. This gravel is suited for biotope recreations and modern layouts that emphasize depth and clarity.
Rio Branco gravel is made of 100% natural material, light- and CO₂-resistant, and inert, meaning it won’t alter your tank’s water chemistry. It’s also safe for all aquatic species, including bottom dwellers, shrimp, and delicate invertebrates. Its texture supports fine-rooted plants and encourages the growth of beneficial bacteria.
