Decorative Aquarium Sand ZOOLOGIA Aqua Natura 0.4–1.2 mm, 5 kg

ZOOLOGIA Aqua Natura decorative aquarium sand with grain size 0.4–1.2 mm in a 5 kg bag is a substrate material designed for aquariums and terrarium accents. The sand offers a fine to medium texture that supports plant rooting and creates a natural-looking substrate layer. It is intended for use in freshwater and planted tanks as well as aquascapes where uniform grain and muted color help highlight plants, fish and hardscape features.

Advantages

The sand provides consistent particle size and an even surface that simplifies layout work and plant placement. Its grain distribution supports root penetration for many aquatic plants while minimizing cloudiness when rinsed before use. Packed in a 5 kg bag, the material is convenient for covering moderate substrate areas or blending with other media to obtain desired depth and contrast.

Suitable for

• Freshwater aquariums
• Planted tanks and aquascaping
• Terrarium decorative layers
• Creating contrast and natural-looking landscapes in tank layouts

Key specifications

• Grain size: 0.4–1.2 mm
• Net weight: 5 kg
• Texture: fine to medium grain
• Color: natural/muted (suitable for enhancing plant and fish visibility)
• Intended environments: freshwater and planted aquaria, terrarium accents

How to use

Rinse the sand thoroughly with clean water until discharge runs clear to remove dust and fines. Spread the sand evenly across the bottom of the aquarium to the desired depth, typically 2–5 cm for general decoration or deeper where plant rooting is required. If using with live plants, create slight slopes or planting areas to support rhizome placement and root growth. Combine with nutrient-rich substrate layers underneath if long-term planted tank fertilization is needed.

Usage recommendations

For initial setup, perform a gentle fill by placing a plate or sheet on the sand surface and pouring water onto it to avoid disturbing the layout. Regular vacuuming of surface detritus during maintenance will help keep the sand clean; avoid deep siphoning that could remove planted roots or create uneven depressions.
