Decorative Polished Black Pebble Stones VidaXL 20–30 mm, Aquarium and Terrarium Gravel, 10 kg

Polished black pebble stones VidaXL 20–30 mm in a 10 kg bag are natural-looking gravel designed for use in aquariums and terrariums. The stones are smooth, uniformly sized between 20 and 30 mm and provide a dense, decorative substrate layer that enhances contrast with plants, driftwood and ornamental features. Their polished surface reduces sharp edges, making them suitable as a stable base for planting and as an aesthetic cover for filtration outlets and equipment.

Advantages

These polished pebbles combine visual appeal with practical functionality: the dark color increases contrast and depth in both freshwater tanks and terrestrial displays, while the rounded shape minimizes damage to delicate roots and soft-bodied animals. The 10 kg packaging supplies enough material for medium-sized setups and allows for even distribution and leveling. Polished finishing reduces dust and small fragments, simplifying rinsing and initial setup.

• Aquarium substrate for freshwater tanks

How to use

Before adding to an aquarium or terrarium, rinse the pebbles thoroughly with fresh water until runoff is clear to remove dust and residues from packaging. Spread an even layer across the bottom of the enclosure; for planted aquariums position a 2–4 cm base layer and add nutrient substrate if required. In terrariums, create gentle slopes or level areas to improve drainage and visual structure. Place filtration outlets, heaters and other devices on top of or behind the pebbles as needed, ensuring equipment remains accessible for maintenance.

Usage recommendations

For aquariums, monitor water parameters after initial placement and perform partial water changes if cloudiness occurs. Avoid using pebbles with aggressive edges near delicate animals. When arranging in terrariums, combine with bark, soil or moss layers where humidity retention or burrowing behavior is required.
