Decorative aquarium sand ZOOLOGIA Orinoco — 5 kg natural-colored substrate

ZOOLOGIA Orinoco decorative aquarium sand in a 5 kg bag provides a natural-colored, fine-grained inert substrate designed for freshwater aquariums. The sand creates a uniform, low-profile bottom layer that supports the aesthetic of biotope layouts and natural-looking aquascapes. Its fine texture is suitable for planted tanks and for species that frequent the substrate surface, while offering a stable base for root development and gentle support for bottom-dwelling fish and invertebrates.

Advantages

This natural-colored sand is inert and does not alter water chemistry, making it compatible with a wide range of freshwater setups. The fine grain size helps anchor plant roots and allows burrowing or sifting species to behave naturally. Packaged in a 5 kg bag, it is easy to handle and proportion for small to medium aquaria. The uniform color and texture support consistent visual results when creating natural scapes, biotopes, or shrimp tanks.

Suitable for

• Freshwater planted aquariums with live aquatic plants
• Biotope and natural-style aquascapes
• Shrimp tanks and invertebrate-friendly setups
• Community aquaria with bottom-dwelling species
• Substrate layering and aquarium floor preparation

Key specifications

• Weight: 5 kg bag
• Color: natural, neutral tone suitable for biotope aesthetics
• Texture: fine-grained sand for stable rooting and gentle substrate interaction
• Chemical nature: inert, does not affect pH or water hardness
• Intended use: freshwater aquarium substrate for plants, shrimp, and bottom-dwellers

How to use

Rinse the sand thoroughly with clean water before adding it to the aquarium to remove dust and fines. Spread the sand evenly across the tank bottom to the desired depth, typically 2–5 cm depending on plant species and tank inhabitants; deeper layers may be used for larger plants requiring more root space. When planting, create small hollows for root placement and gently cover roots without compressing the sand excessively. Combine with nutrient-rich layers or root tabs if cultivating demanding plants, while maintaining caution to avoid mixing materials that could cloud the water.

Usage recommendations

For best results in planted tanks, use a base layer of plant substrate or root fertilizer below the ZOOLOGIA Orinoco sand where necessary, and introduce plants gradually to allow roots to establish. Regular gentle vacuuming of surface debris will keep the fine sand clean without disturbing plant roots. Avoid using in systems where substrate stirring is frequent unless this behavior is intended for species or maintenance routines.
