Aquarium and terrarium polished pebbles NB Minerals Multicolor Pebble 10–20 mm — 5 kg

Aquarium and terrarium polished pebbles NB Minerals Multicolor Pebble 10–20 mm — 5 kg are natural-looking polished stones intended for use as substrate and decorative elements in aquariums and terrariums. The pebbles measure between 10 and 20 mm, come in mixed colors and are supplied in a 5 kg pack. They create stable gravel beds, provide anchorage for plant roots and form hiding spots for small aquatic and terrestrial animals while adding visual texture to aquatic scapes and terrarium landscapes.

Advantages

Polished surface reduces sharp edges, lowering the risk of injuring fish or small reptiles. Mixed colors offer a natural appearance suitable for a wide range of aquarium and terrarium styles. The pebble size distribution (10–20 mm) ensures good water flow through the substrate and supports mechanical filtration when used in filtration accents. Supplied in a 5 kg pack, the product is convenient for small to medium setups and for targeted landscaping or maintenance tasks.

How to use

Rinse the pebbles thoroughly with clean water before adding them to the aquarium or terrarium to remove dust and fine particles. Spread an even layer on the bottom to the desired depth, taking care to create slopes or contours if required for landscaping. For planted aquaria, combine with a nutrient substrate below or use the pebbles as a top layer to weigh down plant roots. In filtration accents, place pebbles where mechanical debris accumulation is desired and clean periodically by gentle rinsing.

Usage recommendations

Perform initial rinsing until the rinse water runs clear. When used in aquariums, avoid sudden substrate changes that could disturb water chemistry; add pebbles gradually and monitor water parameters after installation. For terrariums, ensure the layer supports adequate drainage beneath if required by the species kept. Clean pebbles by manual rinsing rather than using chemical cleaners to preserve a safe environment for animals and plants.
