Aquarium decoration set Bosch WIO Black Allure River — black and light beige substrate, 19 kg, box

Bosch WIO Black Allure River is an aquarium decoration set that contains 19 kg of mixed black and light beige substrate in a box. The blend is designed to create a contrasting riverbed or natural-style layout in freshwater aquariums, offering a visually distinct base for plants, rocks and ornaments. This substrate combination is intended for ornamental aquascaping where color contrast and textural variation are desired.

Advantages

The mixed black and light beige substrate provides clear visual contrast that highlights plant foliage and decorative stones while maintaining a uniform particle size for stable layouts. Supplied in a sealed box with a measured weight, the set simplifies planning for mid-sized aquariums and reduces the need to mix separate substrates. The neutral tones support a wide range of design styles from minimalist riverbed setups to natural planted tanks.

Suitable for

• Freshwater aquariums and terrariums where visual contrast is required
• Riverbed-style and natural biotope layouts
• Planting foregrounds and highlighting rock formations
• Hobbyists preparing substrate layers before adding plants and hardscape

Key specifications

• Total weight: 19 kg of mixed substrate
• Color composition: black and light beige particles
• Packaging: box suitable for storage and gradual use
• Intended use: decorative aquarium substrate for freshwater environments
• Particle characteristics: visually consistent grain size suitable for aquascaping

How to use

Rinse the substrate thoroughly with clean water before adding it to the aquarium to remove dust and fine particles. Spread the substrate evenly to the desired depth, shaping slopes or riverbed contours as required by your layout. Position plants, rocks and driftwood after the substrate is in place; use planting tongs for delicate species to avoid disturbing the layer. When filling the tank, pour water slowly over a plate or plastic bag to minimize displacement of the substrate.

Usage recommendations

For planted aquariums, consider adding a nutrient layer or root tabs beneath the decorative substrate if using root-feeding plants. Regular partial water changes and gentle vacuuming of the surface will maintain clarity without significantly disturbing the substrate pattern. Avoid sudden changes in water chemistry and large-scale digging by bottom-dwelling species to preserve the designed layout.
