Seiryu Stone is one of the most sought-after hardscape stones in aquascaping, prized for its dramatic ridges, sharp textures, and striking grey-blue tones with natural white calcite veins. It is a favourite choice for Iwagumi-style layouts, creating powerful structure, depth, and contrast in planted aquariums.
Its bold, craggy appearance makes it ideal as a focal stone while smaller supporting pieces help create a natural mountain or cliff aesthetic.

Seiryu Stone contains calcium carbonate and may raise KH and GH over time. It is suitable for most planted tanks but may not be ideal for very soft-water setups without monitoring and management.
Testing is recommended for Caridina shrimp or sensitive species.
Rinse thoroughly before use. For secure stacking, place larger stones directly on the aquarium base before adding substrate. Each piece is unique in size, shape, and veining.
