AQUA DELLA aquarium gravel Żwirek Alps 4–8 mm, 10 kg

AQUA DELLA aquarium gravel Żwirek Alps 4–8 mm, 10 kg is a natural-looking substrate designed for freshwater and planted aquariums. The gravel consists of rounded grains sized 4–8 mm that create a stable base for décor and aquatic plants while allowing water to move through the substrate. Supplied in a 10 kg bag, this product is intended to support plant root anchoring and contribute to biological filtration when combined with regular aquarium maintenance. Rinse the gravel before use to remove any dust or fines.

Advantages

The substrate offers uniform grain size that promotes even water circulation around plant roots and reduces compacting. Its neutral appearance complements a variety of aquascape styles without altering water chemistry. The 4–8 mm grain size balances stability for plant anchoring and openness for beneficial microorganism activity. Supplied in a 10 kg pack, it is suitable for creating consistent coverage across small to medium aquarium bases.

Suitable for

• Freshwater community aquariums
• Planted tanks requiring stable root substrate
• Aquascapes and natural-looking layouts
• Use as a top layer over nutrient-rich substrates or as a standalone decorative substrate

How to use

Before adding to the aquarium, rinse the gravel thoroughly under running water until the rinse water runs clear to remove dust and fines. Add a layer of 2–5 cm for basic decoration or 5–8 cm where plant anchoring and root development are required; adjust depth according to plant species and tank layout. Place plants and décor on top of the gravel and fill the aquarium slowly to avoid disturbing the substrate. Monitor water clarity for the first few hours and perform additional rinsing or water changes if necessary.

Usage recommendations

For planted setups, consider using this gravel as a top layer over a nutrient-rich substrate or adding root tabs for heavy root feeders. Maintain regular vacuuming of the top gravel layer during water changes to remove accumulated detritus while preserving beneficial bacteria in deeper layers.
