Aquasand ASHEWA aquarium substrate ZOLUX 750 ml — black decorative sand

ZOLUX Aquasand ASHEWA aquarium substrate is a 750 ml volume of black decorative sand formulated for freshwater aquariums. This finely textured sand creates a natural-looking base layer that enhances the visual contrast of plants and fish while providing a stable bedding for bottom-dwelling species and aquascape layouts. The dark tone highlights colors and shapes within the tank and helps define planted areas and ornamental compositions.

Advantages

The black decorative sand offers a consistent grain size and uniform color that resists clouding when properly rinsed. It is suitable as a purely aesthetic top layer or combined with nutrient substrates beneath for planted aquaria. The sand’s colour improves visibility of fish and plant tones, while its fine texture supports burrowing behaviour of small bottom-dwelling fish and invertebrates. The product is supplied in a compact 750 ml package that is easy to measure and distribute across small to medium aquarium bases.

Suitable for

• Freshwater community tanks with live plants
• Planted aquariums when used above nutrient substrate
• Tanks housing bottom-dwelling fish and small invertebrates
• Ornamental aquascapes and display aquaria seeking high visual contrast

How to use

Before adding to the aquarium, rinse the sand under running water until the discharge runs clear to reduce initial clouding. Spread an even layer on the aquarium bottom; for planted setups, place the sand over a nutrient-rich substrate or specific plant substrate to support root development. Aim for a depth appropriate to plant species and bottom-dwellers—typically 2–4 cm for decorative use in small to medium tanks. Introduce water gently over a plate or plastic bag to avoid disturbing the sand layer when filling the tank.

Usage recommendations

Rinse thoroughly before use and combine with a nutrient substrate where live plants require root access to minerals. Periodically vacuum surface detritus during maintenance to preserve clarity and prevent compacting; avoid heavy stirring to maintain aesthetic layering and habitat structure for bottom-dwelling species.
