Aquarium substrate gravel sera Aquarium Soil White 1–3 mm 6000 ml

sera Aquarium Soil Gravel White 1–3 mm 6000 ml is a white aquarium substrate intended for freshwater aquariums and planted or community setups. The substrate consists of uniformly sized 1–3 mm gravel that creates a stable base for plants, décor and hardscape, while contributing to a clean, bright aesthetic. The 6000 ml volume covers a substantial area at typical substrate depths, and the material is easy to rinse and distribute to achieve even aquarium landscaping.

Advantages

The fine gravel grain size (1–3 mm) supports root penetration and plant anchorage without compacting excessively. Its white colour enhances light reflection within the aquarium, improving plant visibility and the appearance of aquatic life. The substrate is suitable for layered arrangements with nutrient-rich soils and is simple to handle during setup: it rinses clean and spreads evenly to form a stable bed.

Suitable for

• Planted freshwater aquariums requiring a neutral, light-coloured substrate
• Community tanks where a stable and decorative base is needed
• Aquascaping projects using light-coloured hardscape and décor
• Temporary or permanent substrate cover over nutrient layers

Key specifications

• Grain size: 1–3 mm
• Volume: 6000 ml
• Colour: white
• Intended use: freshwater aquariums, planted and community tanks
• Physical form: loose gravel suitable for rinsing and distribution

How to use

Before adding to the aquarium, rinse the gravel thoroughly in tap water until the rinse water runs clear to remove dust and fines. Place the substrate in a uniform layer or in contours according to your aquascape plan; typical depths for planted tanks range from a thin cover to several centimetres depending on plant species and whether nutrient substrates are used underneath. Add plants, rocks and décor on top of the prepared layer and fill the aquarium slowly to avoid disturbing the layout.

Usage recommendations

For optimal plant growth, combine this white gravel with a nutrient-rich substrate or root tabs where species require additional nutrients. Avoid using directly over bare glass if you require very deep nutrient layers; instead create a layered substrate to retain nutrients while maintaining the white gravel surface for aesthetics. Regular vacuuming of surface detritus during maintenance will help keep the white appearance intact.
