Decorative Aquarium Gravel ZOOLOGIA Aqua Natura Padamo natural 1–2 mm 5 kg

Decorative Aquarium Gravel ZOOLOGIA Aqua Natura Padamo natural 1–2 mm 5 kg is a fine natural gravel designed for freshwater aquariums, terrariums and aquascaping. With a grain size of 1–2 mm and a 5 kg package, this substrate creates a natural-looking bottom layer that supports plant root anchorage and allows beneficial bacteria to colonize. The neutral natural color tones blend with a variety of aquatic layouts and help emphasize plant and fish coloration without altering water chemistry when used as intended.

Advantages

This natural gravel offers a fine-grain texture that is gentle on delicate plant roots and small bottom-dwelling fish. Its uniform grain size promotes even water flow through the substrate and facilitates gas exchange in the lower layers. The material is packaged in a practical 5 kg bag, making it easy to handle and spread during aquarium setup or maintenance. Because it is designed for freshwater use, it supports typical planted-tank ecosystems and aquascapes without active buffering of pH.

Suitable for

• Freshwater aquariums with live plants and small fish
• Terrariums requiring a natural, fine substrate layer
• Aquascaping projects that need a uniform 1–2 mm gravel
• Biotope setups where neutral-colored substrate is desired

When it may not be suitable

This gravel is intended for freshwater applications and is not formulated to significantly alter water parameters; it may not be suitable when substrate-induced pH or hardness modification is required. It is also a fine-grain material, so in tanks with very large digging species or heavy burrowers the gravel may shift or be displaced over time.

Key specifications

• Grain size: 1–2 mm
• Net weight: 5 kg
• Colour tone: natural/neutral
• Intended use: freshwater aquariums, terrariums, aquascaping
• Texture: fine, uniform particles suitable for plant roots and bacterial colonization

How to use

Rinse the gravel thoroughly with clean water before adding it to the aquarium to remove dust and fines. Place the substrate in an even layer across the aquarium floor; depth can be adjusted according to planting needs, typically 2–5 cm for most planted setups. Add plants and décor, then fill the tank slowly to avoid disturbing the substrate. Monitor water clarity during the first few fills and perform a partial water change if needed after installation. Routine vacuuming of the surface during maintenance will keep the gravel clean while preserving the lower biological layer.

What to consider before purchase

• Suitable for freshwater systems; not intended to change pH or hardness
• Grain size 1–2 mm is best for small plants and small-bottom fish
• Consider required substrate depth for plant types and biological filtration
• Rinsing before use is recommended to remove dust

Usage recommendations

For planted aquariums, use a 2–5 cm layer of this 1–2 mm gravel on top of any nutrient layer or root substrate. Combine with regular partial water changes and gentle surface vacuuming to maintain clarity without disrupting beneficial bacteria in the lower layers.
