Seiryu Stone Per 1KG

Seiryu Stone is one of the most famous and widely used hardscape materials in aquascaping, heavily popularized by Takashi Amano in Iwagumi-style layouts. Characterized by its bluish-grey color, rugged mountain-like textures, and striking white calcite veins , it is prized for creating immediate depth and dramatic contrast against green aquatic plants.

Because true Japanese Seiryu Stone faces strict export bans, most "Seiryu" sold in the hobby today is closely related, acid-treated limestone that perfectly mimics its original aesthetic.

Water Chemistry Impact 💧

Because Seiryu Stone is limestone-based, it will alter your water parameters. As water flows over the rock, it slowly releases calcium carbonate into the tank:

pH, KH, and GH will gradually increase over time.
The "buffering ceiling" naturally halts this dissolution once the water stabilizes into an alkaline range (typically between 7.6 and 7.9 pH).
Livestock Compatibility: This effect is excellent for livebearers, shrimp (like Cherry or Amano), and African Rift Lake cichlids. However, it can make it more challenging to keep soft-water-loving species like Caridina shrimp or delicate acid-loving plants.
Seiryu Stone Variants
- Standard Seiryu Stone: Features traditional light grey to slate tones with high-contrast white veining.
- Dark Seiryu Stone: Natural Seiryu that has undergone an industrial acid-washing process. This etches the surface to reveal deep charcoal and slate-black colors, creating an even more dramatic backdrop for bright green mosses and plants.
Essential Tips for Using Seiryu Stone
- Preparation: Do not skip scrubbing and rinsing the stones. They accumulate significant rock dust during transit, which can instantly cloud your aquarium water.
- Countering Hard Water: If you want to keep the water softer in a Seiryu layout, you can inject carbon dioxide (CO₂), use active aqua soil (which naturally lowers pH), or perform routine water changes using Reverse Osmosis (RO) water.
- Layout Design: When building a scape, plug the gaps between larger rocks using filter floss or smaller accent stones. This prevents your background substrate from sliding forward or trapping pockets of anaerobic detritus
