## Long description

Aquarium and Terrarium Black Lava Stones 30–50 mm from NB Minerals are natural crushed volcanic rocks supplied in a 5 kg pack. These inert black lava stones are intended for use as decorative substrate elements and structural features in freshwater aquariums, planted tanks, and reptile or amphibian enclosures. With a grain size of 30–50 mm, the stones provide coarse texture for creating caves, ledges and stable hardscape layers while allowing water circulation through decor.
Advantages
Black lava stones are chemically stable and do not alter water parameters, making them suitable for sensitive aquarium and terrarium setups. Their porous surface increases surface area for beneficial bacterial colonization, and the irregular shapes interlock to form stable structures. The 30–50 mm grain size offers a balance between visual impact and practical handling for aquascaping, terrarium landscaping and creating hiding spots for fish, reptiles and amphibians.
Suitable for
Freshwater aquariums, including planted tanks
Terrariums and vivariums for reptiles and amphibians
Hardscape construction: caves, ledges and stable decor bases
Biological filtration support by providing surface area for bacteria
Key specifications
Material: natural volcanic lava rock (inert)
Grain size: 30–50 mm
Color: black
Pack weight: 5 kg
Form: crushed stones with irregular shapes and porous surfaces
How to use
Rinse stones thoroughly with fresh water before placing them in an aquarium or terrarium to remove dust and fines. Arrange stones to create stable structures, avoiding tall, unsupported stacks that could collapse. In aquariums, position stones to allow free water flow around and through decor; in terrariums, combine with suitable substrate to ensure stability and proper humidity management. Monitor water parameters after adding to a new aquarium and observe enclosure inhabitants to confirm suitability.
Usage recommendations
Use these black lava stones as a decorative and structural element rather than a complete substrate layer for planted tanks; combine with nutrient substrates where plant rooting is required. Handle stones with care when arranging to avoid scratching glass or acrylic. Regularly check and clean stones as part of routine maintenance to prevent debris buildup.
