Aquarium Gravel, sera Gravel White, 1–3 mm grain, 3 L, white

sera Gravel White aquarium gravel, grain size 1–3 mm in a 3 L pack, is a natural-looking white substrate designed for freshwater aquariums and planted tanks. This inert gravel provides a stable base for plants and decorations without altering water chemistry. Its rounded grains create a firm bedding that anchors plant roots, increases surface area for beneficial bacteria, and enhances overall aquarium aesthetics with a clean, bright appearance.

Advantages

The neutral composition of this white gravel means it will not change pH or hardness, making it suitable for a wide range of freshwater setups. The 1–3 mm grain size balances water flow through the substrate with root support for common aquatic plants. Its light color improves visual contrast with fish and plants and simplifies spotting debris during maintenance. Being pre-washed and aquarium-safe, the gravel reduces initial cloudiness and is ready for installation.

Suitable for

• Freshwater community aquariums
• Planted tanks with root-feeding and substrate-rooted plants
• Display or biotope aquariums where neutral substrate is required
• Terraces of shrimp and small invertebrate setups

Key specifications

• Grain size: 1–3 mm
• Color: white
• Pack volume: 3 L
• Chemical nature: inert, does not alter water parameters
• Surface: rounded grains to reduce sharp edges

How to use

Rinse the gravel briefly if a small amount of dust is present, then distribute it evenly along the aquarium floor to the desired depth (typically 2–5 cm depending on plant types). For planted aquariums, combine with nutrient substrates or root tabs if additional fertilization is needed, placing nutrient layers beneath or mixed with the gravel as appropriate. Arrange plants and decorations, then fill the tank slowly to avoid disturbing the substrate. Monitor water clarity during initial filtration cycles and perform partial water changes if necessary.

Usage recommendations

Use this gravel in combination with liquid fertilizers or root tabs for healthy plant growth; avoid sharp gravel mixing to prevent injury to bottom-dwelling species. Regular vacuuming of the top layer during maintenance helps remove accumulated detritus while preserving beneficial bacterial colonies.
