Aquarium and terrarium black crushed stones VidaXL 20–30 mm, 10 kg pack

Black crushed stones by VidaXL sized 20–30 mm, packed as a 10 kg unit, provide a natural-looking mineral substrate for aquariums, terrariums and decorative plant displays. These stones are intended for use as a substrate layer, decorative gravel or drainage material, helping to stabilise plants and improve water flow in both freshwater and terrestrial setups.

Advantages

The black crushed stones offer consistent particle size of 20–30 mm and a neutral mineral composition suitable for decorative and functional use. Their weight and texture help anchor larger aquatic and terrestrial plants and create stable terrain for reptiles and invertebrates. As a natural material, the stones do not contain synthetic colouring and can be combined with other substrates or drainage layers to tailor appearance and functionality.

How to use

Rinse the stones thoroughly with clean water before introducing them to aquariums, terrariums or planters to remove dust and small particles. For aquariums, place the stones as a decorative top layer or mix with finer substrate; ensure an even, stable bed and avoid sharp edges near glass. In terrariums use the stones as a drainage layer beneath soil or as part of the visible floorscape to create varied texture. In planters place a layer at the base to improve drainage, or use them on the surface for a decorative finish.

Usage recommendations

Inspect stones for unusually sharp fragments before use and remove any dust by repeated rinsing. Do not use in marine aquariums without prior compatibility checks for saltwater chemistry. Combine with appropriate substrate and filtration for aquarium health and with suitable soil and humidity control in terrariums.
