## Long description

NB Minerals Black Lava Stones (50–80 mm, 5 kg pack) are porous volcanic rocks intended for decoration and functional use in aquariums, terrariums and paludariums. The natural black texture provides visual contrast and structure while the porous surface increases surface area for beneficial bacteria, supporting biological filtration. Stones come clean and uncoated, ready to place directly into freshwater setups or reptile enclosures to create hiding spots, stable substrate edges and varied terrain.
Advantages
These lava stones combine aesthetic and practical properties: porous structure for improved bacterial colonization, irregular shapes to form natural-looking crevices and shelters, and medium sizes that are easy to arrange. The stones are inert and require no additional coatings or treatments, so they maintain water chemistry when introduced into freshwater aquaria and do not release dyes or additives. Their weight and shape help anchor substrate and décor elements, contributing to stable layouts.
Suitable for
Freshwater aquariums with fish, shrimps and snails
Paludariums and planted setups requiring hardscape
Terrariums and reptile enclosures for hiding places and climbing surfaces
Biological filtration support in filters, sumps or wet/dry sections
Key specifications
Material: natural volcanic lava (porous basaltic rock)
Size range: approximately 50–80 mm per stone
Pack weight: 5 kg
Color: natural black
Surface: porous, rough texture for microbial colonization
C hemical property: inert in freshwater (no coatings or additives)
How to use
Rinse stones thoroughly with clean water before placement to remove loose dust or fines. Arrange stones directly in the aquarium, terrarium or paludarium to create desired hardscape — stack or nestle them to form caves and ledges, or spread them across the substrate to provide textured areas. For aquaria, place heavier stones on compacted substrate or on a stable base to avoid pressure points on glass. No special preparation is required beyond rinsing, as stones are supplied uncoated and ready for use.
Usage recommendations
Monitor water parameters after introducing new hardscape; while these lava stones are inert in freshwater, small shifts in pH or hardness can occur in sensitive systems. For planted tanks, combine with appropriate substrate and root tabs as needed. In terrariums, ensure stones are secured to prevent collapse and provide thermal gradients appropriate for the resident species.
