## Long description

ZOOLOGIA Aqua Natura Orinoco river gray decorative aquarium gravel features mixed grains sized 2–8 mm and net weight 0.8 kg, designed for use in freshwater aquariums. The gray color and natural grain shapes create a riverbed-like appearance suitable for planted tanks, aquascapes and habitats for bottom-dwelling fish. The substrate is intended to provide visual enhancement, support layout structures such as terraces and rockwork, and allow planting and stable placement of ornaments without altering water chemistry when used as directed.
Advantages
The gravel offers a consistent grain size distribution (2–8 mm) that supports root placement for plants and stable positioning of decorations. Its neutral gray color complements a wide range of aquatic plants and fish, enhancing contrast without introducing dyes or chemical additives that change water parameters. Lightweight packaging and a modest 0.8 kg quantity make it easy to handle and dose for small to medium aquariums or to test appearance before larger purchases.
Suitable for
 Freshwater community and planted aquariums
 Bottom-dwelling fish species and invertebrates
 Aquascaping with terraces, rocks and driftwood
 Small demonstration tanks and nano aquariums
Key specifications
 Grain size: 2–8 mm
 Color: river gray
 Net weight: 0.8 kg
 Intended water type: freshwater
 Use: decorative substrate for planting and hardscape support
How to use
Rinse the gravel thoroughly under running water until the rinse water runs clear to remove dust and fines. Spread an even layer on the aquarium bottom; typical depth for general use is 2–4 cm, deeper layers may be used for plant root development or terracing. Place plants, rocks and decorations as required, and refill the aquarium slowly to avoid disturbing the substrate. Monitor water clarity during the first few hours after filling and perform gentle filtration until any remaining particles settle or are removed.
Usage recommendations
For planted tanks, combine this gravel with a nutrient-rich substrate layer beneath if active root-feeding plants are used. Avoid using in aquaria where fine substrate is specifically required for digging species. Regular vacuuming around decor and plant bases will keep the gravel clean while preserving the substrate profile.
