Aquarium substrate ZOLUX Aquasand EKAI blue 1 kg

ZOLUX Aquasand EKAI blue is a decorative aquarium substrate supplied in a 1 kg package designed for freshwater tanks. The product provides a uniform blue sand layer that enhances visual contrast in planted and ornamental aquariums. It is intended as a top substrate or decorative surface layer to highlight plants, rocks and fish coloration while contributing to a clean, finished look in home aquascapes.

Advantages

The blue sand offers consistent grain size and color stability to maintain an even appearance over time. As a decorative top layer it is easy to spread and reposition during aquascaping, enabling quick changes to layout and contrast. The material is compatible with common freshwater aquarium setups and does not require special substrates underneath when used as a surface layer.

Suitable for

• Freshwater home aquariums as a decorative surface layer
• Highlighting aquatic plants, stones and driftwood in aquascapes
• Creating visual contrast to showcase fish coloration
• Temporary displays, breeder tanks or photo tanks where a colored substrate is desired

Key specifications

• Color: Blue
• Package weight: 1 kg
• Material form: Decorative sand
• Intended use: Top substrate / decorative surface layer for freshwater aquariums
• Grain characteristics: Fine, uniform particles suitable for surface application

How to use

Rinse the sand briefly with tap water until the runoff becomes clear to remove any dust from packaging. Spread an even layer of sand across the aquarium bottom; recommended depth for a decorative top layer is typically 1–3 cm depending on tank size and planting preference. Position plants, rocks and ornaments on top of the sand and fine-tune the layout. When performing maintenance, siphon debris from the surface carefully to avoid excessive removal of the decorative layer.

Usage recommendations

Use this product as a decorative surface layer rather than a sole nutritive substrate for heavy root-feeding plants. Combine with an appropriate base substrate or root tabs when long-term planting or nutrient supply is required. Avoid mixing with strongly contrasting substrates if uniform color is desired.
