Most of the Seiryu stones being sold outside of Japan are typically Ryouh Stones and are just commonly misidentified. Even through Ryouh Stones are still worth their lbs.

Seiryu Stone Description

The famous Seiryu Stone is blueish grey in color with sharp jagged edges. Most of them consist of deep cuts and crevices within the stone itself. Seiryu Stones frequently have calcite veins within their layers, creating a great contrast from its brilliant blueish grey hue to its stripes of white veins.

Seiryu stones will definitely raise your pH and gH depending on how many pounds per gallon you have added into your tank. They are completely shrimp safe for Red Cherry Shrimp, Ghost/Glass Shrimp, and Amano Shimp. When getting into Crystal Red shrimp, it becomes a bit risky and you have to be cautious or counteract your rocks if they are affecting the water parameters too much.

RO water or driftwood will help counteract the water effects of Seiryu Stones.
