Ryuoh Stone per kg

Ryuoh Stone is a premium Japanese aquascaping rock prized for its sharp angular shapes, white-grey color, and dramatic crevice formations. It is slightly softer than Seiryu Stone but creates similarly striking visual landscapes. Its hard, compact surface provides excellent anchor points for mosses and epiphytic plants. Like other calcite-containing rocks, it may raise pH and hardness, making it better suited for neutral to alkaline water setups or with careful water chemistry monitoring.
