Aquarium Decorative Gravel LEGO Aqua Natura mix 5 colors 2–4 mm, 5 kg

LEGO Aqua Natura decorative gravel, mixed in five colors with a grain size of 2–4 mm and a net weight of 5 kg, is designed for use in freshwater aquariums as a visually striking substrate layer. This non-toxic aquarium gravel is suitable for hobby aquarists and aquascaping projects where consistent grain size and color variety help create contrast with plants and fish. The product is intended to be rinsed thoroughly before placement and used as a decorative top layer or full substrate depending on tank setup and plant requirements.

Advantages

The gravel provides a uniform grain size (2–4 mm) that supports stable layering and even coverage across the tank bottom. A five-color mix enhances visual depth and contrast without introducing additives that could affect water chemistry when used correctly. The 5 kg package offers enough material to cover moderate aquarium bases or to add decorative accents to larger tanks. As a purpose-made decorative gravel, it is produced to be non-toxic and compatible with standard freshwater aquarium conditions.

Suitable for

• Freshwater community aquariums
• Planted tanks as a decorative top layer (use with nutrient substrates if required)
• Breeding and display aquariums to improve visual contrast for fish
• Aquascaping projects and themed tank layouts
• Temporary displays or decorative bowls (after proper rinsing)

How to use

Before use, rinse the gravel under running water until the water runs clear to remove dust and fine particles. Place a 1–3 cm layer for decorative purposes or increase depth according to plant root requirements and tank size; when cultivating rooted plants, consider using a nutrient substrate beneath this gravel. Spread the gravel evenly across the tank bottom and arrange decorations or plants as desired. After filling the aquarium, cycle the tank according to standard aquarium practice before adding sensitive livestock.

Usage recommendations

Rinse thoroughly before adding to the aquarium to avoid clouding. Use in freshwater setups and combine with appropriate plant substrates for healthy rooted plant growth. Monitor water parameters after initial placement and perform regular maintenance such as vacuuming the surface during water changes to prevent debris buildup.
