Aquarium and terrarium polished jade stones 10–20 mm, Terra Natura, 5 kg pack

Aquarium and terrarium polished jade stones 10–20 mm from Terra Natura are natural-looking decorative gravel supplied in a 5 kg pack. The stones feature a rounded, polished surface and a consistent grain size between 10 and 20 mm, making them suitable as substrate elements, decorative accents, or stable footing in freshwater aquariums, paludariums and reptile enclosures. The material is inert and does not release additives into the water or enclosure environment, allowing it to be used with plants, décor and animals without affecting basic water chemistry when rinsed properly before use.

Advantages

These polished jade stones provide a balanced combination of aesthetics and function: their smooth surfaces reduce the risk of injury to fish and reptiles while offering an attractive, natural appearance. The uniform 10–20 mm grain size creates stable surfaces for planting, décor placement and animal movement. Because the stones are inert, they do not leach minerals or chemicals into freshwater systems, and their polished finish is easy to rinse and maintain. A 5 kg pack supplies enough material for medium-size setups or focal areas within larger enclosures.

Suitable for

• Freshwater aquariums as decorative gravel or substrate accents
• Paludariums and planted tanks for stable planting pockets and hardscape
• Terrariums and reptile enclosures to create walking surfaces and visual contrast
• Decorative arrangements and terrarium landscaping projects

Key specifications

• Material: polished natural stone (jade appearance)
• Grain size: 10–20 mm
• Finish: smooth, polished surface
• Pack weight: 5 kg
• Chemical behavior: inert in freshwater when rinsed

How to use

Rinse the stones thoroughly under running water until the rinse water runs clear to remove dust and fine particles. Spread the stones evenly over the substrate or place them selectively to create decorative zones, planting pockets or defined pathways. When used in aquaria, add the stones before filling the tank or during a partial water change to avoid disturbing existing décor excessively. In terrariums and paludariums, position the stones to provide areas of stable footing, hide spots or visual contrast with plants and bark.

Usage recommendations

For best results, rinse the stones before first use and periodically inspect them for trapped debris. Avoid using these stones in delicate softwater or specialized buffering systems where any change in mineral content must be tightly controlled; although inert for typical freshwater setups, always monitor water parameters after adding new substrate materials. Combine with appropriate substrate depth and filtration for the specific species kept.
