Golden Tree Riverbed Gravel is a natural, multi-toned substrate frequently used in aquariums, aquascapes, and terrariums.
Key Characteristics
Appearance: It features a mix of natural grey, tan, brown, and cream-coloured stones that replicate a realistic riverbed environment.
Water Safety: The gravel is completely inert, meaning it will not alter your water chemistry, pH levels, or water hardness. This makes it safe for sensitive freshwater fish, shrimp, and live plants.
Size Variations: It is commonly available in multiple grain sizes to suit different styles, including fine variations (5–10mm) for small tanks, medium gradings (10–20mm), and coarser stones (1–3cm) for heavy riverbed texturing.
Golden Tree Black Stone Gravel is a premium, dark-toned substrate designed for freshwater aquariums, biotopes, and custom aquascapes.
Key Characteristics
Appearance: It features a striking, uniform dark colouration. This deep black aesthetic provides a bold contrast that makes the vibrant greens of aquatic plants and the natural colours of fish or shrimp stand out prominently.
Water Safety: The substrate is completely inert and aquarium-safe. It will not leach minerals into the water, meaning it won't alter your pH, water hardness, or overall water chemistry.
Texture & Cleanliness: Sourced from high-quality natural materials, it is processed to be super clean and low in dust. This helps keep water cloudiness to a minimum during initial tank setups, though a quick, light rinse before adding it to the tank is always recommended.
Common Sizing: It is widely available in a medium 9–12mm grain size, making it a great choice for standard bottom coverage or texturing around larger rock and driftwood layouts.
Common Uses for both
Aquascaping: Used as a stark, dramatic base layer to create modern, high-contrast underwater landscapes.
Shrimp & Fish Habitats: Highly popular for shrimp tanks and community aquariums because dark substrates help reduce fish stress and encourage them to display their brightest, most intense natural colours.
Terrariums: Can also be utilized as a decorative top layer in terrestrial setups, vivariums, or indoor potted plants to give a clean, polished look.
