Crushed Tumbled Red Aquarium and Terrarium Stones NB Minerals 10–20 mm, 5 kg

Crushed Tumbled Red Aquarium and Terrarium Stones NB Minerals 10–20 mm, 5 kg are natural mineral stones designed for decorative and functional use in aquariums, terrariums and other small habitat projects. The stones feature a polished, tumbled surface and a 10–20 mm particle size, supplied in a 5 kg bag for easy placement. Their natural red coloration is suitable for creating contrast with plants, driftwood and substrate layers while providing stable footing and localized drainage where needed.

Advantages

The stones combine natural mineral composition with a tumbled finish, reducing sharp edges and minimizing risk to aquatic and terrestrial inhabitants. The 10–20 mm grain size balances visual impact and practicality: individual stones are large enough to form structure and accents but small enough to be repositioned for hardscape arrangements. Supplied in a convenient 5 kg pack, the stones are suitable for multiple layout options without the need for custom sorting.

Suitable for

• Aquarium substrate decoration and accent zones
• Terrarium hardscape, basking and drainage layers
• Planted tanks for rockwork and foreground elements
• Reptile and amphibian habitats requiring natural cover and textured surfaces

Key specifications

• Particle size: 10–20 mm

• Color: natural red tones
• Material: natural mineral stone

How to use

Rinse the stones thoroughly under running water before placing them into aquariums or terrariums to remove dust and loose particles. Arrange stones as desired to create focal points, borders or drainage layers; for aquariums, place stones on top of or mixed with existing substrate to achieve the intended aesthetic and structural effect. Avoid abrupt placement near fragile equipment or silicone seams in glass tanks. For terrarium use, combine the stones with substrate mixes to improve drainage or build elevated basking platforms and hiding spots.

Usage recommendations

Perform a compatibility check with water chemistry for sensitive species: if using in soft or acidic-water aquaria, monitor pH and hardness after adding mineral stones. For terrariums, place stones where they will not trap excessive moisture against enclosure walls. Clean periodically by removing and rinsing to maintain appearance and prevent detritus buildup.
