## Summary description

Polished red pebble gravel from NB Minerals for aquariums and terrariums, sized 30–50 mm and supplied in a 10 kg package. These smooth decorative stones serve as substrate or landscape elements, suitable for freshwater setups, terrarium floor cover, and ornamental arrangements. Use for anchoring plants, improving aesthetics, and creating natural-looking habitats.

## Long description

Polished red pebble gravel from NB Minerals, sized 30–50 mm and supplied in a 10 kg package, is designed for use in aquariums and terrariums as a decorative substrate or landscape element. The smooth, rounded pebbles create a natural base layer, suitable for freshwater aquaria, paludariums, and a variety of terrarium designs. These stones can be used to anchor plants, define paths and elevations, or form focal points within planted displays while contributing to a stable and visually coherent environment.
Advantages
The pebbles are polished for a smooth surface that reduces sharp edges and minimizes harm to delicate species. Their uniform size range of 30–50 mm allows for consistent layering and predictable drainage behavior. Being natural mineral stones, they maintain colour and texture without chemical treatments that could alter water chemistry when rinsed properly. The 10 kg package provides a practical quantity for creating visible landscaping features or covering substrate areas in small to medium installations.
Suitable for
Freshwater aquariums as a decorative bottom layer
Terrarium floor covering for reptiles, amphibians and invertebrates
Paludariums and riparian landscape accents
Plant anchoring in larger aquascape arrangements
Ornamental displays, garden planters and decorative arrangements
Key specifications
Material: polished natural mineral pebbles
Grain size: 30–50 mm (diameter range)
Colour: red (polished finish)
Weight per package: 10 kg
Surface: smooth, rounded pebbles
How to use
Before use, rinse the pebbles thoroughly with clean water until the runoff is clear to remove dust and fines. Spread stones evenly on the tank or terrarium floor to the desired depth, taking care to leave sufficient space for animal movement and plant roots. When used in aquariums, ensure that the substrate layer does not trap excessive detritus by allowing water flow or by combining with coarser base layers. For terrariums, arrange pebbles to create slopes, drainage zones, or decorative clusters according to habitat needs.
Usage recommendations
Do not use untreated pebbles directly in closed aquatic systems without rinsing. Regularly inspect for accumulated debris and clean by gentle siphoning or removal for rinsing. Avoid using these stones with species that require very soft, acidic water unless water parameters are monitored and adjusted, since mineral substrates can influence hardness if left untested.
