{"product_id":"wio-boulder-ryuohseiryu-boulder","title":"WIO Boulder - Ryuoh(Seiryu) Boulder","description":"\u003cp\u003eA WIO first: the rounded expression of the iconic Ryuoh. We introduced Ryuoh in boulder form so you can keep the mountain DNA, deep greys and pale mineral veins, while composing with softness and flow. The result is a stone that reads calm and timeless, perfect for Iwagumi minimalism and convincingly natural river-stream tanks.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eWhere classic Ryuoh cuts sharp ridges, Ryuoh Boulders are water-shaped: rounded silhouettes, softened seams, and quiet veining that glows under light. Drop a single piece in pale sand and the scene exhales; group a kit and you get meanders, bars, and eddies that feel discovered rather than arranged. Side light draws silvery highlights along the arcs; top light settles everything into a serene, mist-grey hush.\u003c\/p\u003e\n\u003cp\u003eScaping is effortless when you let “current” lead the composition. Seat one main boulder slightly off-axis to set direction, then nest smaller pieces downstream to create natural banks and resting pockets. Half-bury a few to suggest sorting; leave negative corridors where water would move. For seamless scale transitions, veil the bases with \u003cstrong\u003eWIO Accents Grey Chips\u003c\/strong\u003e, and echo the language with classic Ryuoh Stones for subtle ridge contrasts that frame the rounded masses.\u003c\/p\u003e\n\u003cp\u003eFunction matches beauty. The contours are livestock-friendly; crevices invite moss and epiphytes, use \u003cstrong\u003eWIO PlantGlue\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003efor quick establishment. As a calcareous limestone, Ryuoh Boulders may gently nudge pH and hardness over time, easy to manage with routine soft-water changes or buffering, while you enjoy that unmistakable Ryuoh presence translated into soothing, river-true forms.\u003c\/p\u003e\n\u003cul class=\"YInLPU\" data-hook=\"collapse-info-section\"\u003e\n\u003cli class=\"KHWbzo undefined\" data-hook=\"collapse-info-item\"\u003e\n\u003ch2 class=\"swuhcNP oAVDMI_---typography-11-runningText oAVDMI_---priority-7-primary _HOcyB x4nptw sxbtulv ftb6e2\" aria-hidden=\"false\" data-hook=\"info-section-title\"\u003eKey Points\u003c\/h2\u003e\n\u003cdiv class=\"aecizt ciGGdC QfrfFD cell\" data-hook=\"collapse-info-minus-icon\"\u003e\u003csvg viewbox=\"0 0 15 15\" fill=\"currentColor\" width=\"15\" height=\"15\"\u003e\u003cg id=\"Page-2\" stroke=\"none\" fill=\"none\" stroke-width=\"1\" fill-rule=\"evenodd\"\u003e\u003cg id=\"Desktop-1920-\/-1080\" fill=\"currentColor\" fill-rule=\"nonzero\"\u003e\u003cg id=\"new_minus\" transform=\"translate(2 7)\"\u003e\u003cg id=\"Rectangle-5\"\u003e\u003cg id=\"Page-1\"\u003e\u003cg\u003e\u003cg id=\"Group\"\u003e\u003cpath d=\"M0 0L11 0 11 1 0 1z\"\u003e\u003c\/path\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/g\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv aria-hidden=\"false\" class=\"rah-static rah-static--height-auto\"\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"ulKuLk QfrfFD cell\"\u003e\n\u003cdiv data-hook=\"info-section-description\" class=\"zp8uy2\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Deep grey with white marbling and soft transitions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKIT Boulder Sizes:\u003c\/strong\u003e \u003cstrong\u003eNano\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3–16 cm;\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eBox\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3–17 cm;\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eMega\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3–22 cm (typical mix).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTexture:\u003c\/strong\u003e Naturally rounded, water-worn faces; soft, sculptural forms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e Natural limestone (calcareous).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatching:\u003c\/strong\u003e Pairs with\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eWIO Grey Chips\u003c\/strong\u003e; complements Ryuoh Stones or contrasting driftwood.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResults:\u003c\/strong\u003e Organic flow, gentle valleys, and river-bed realism.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReady to Use:\u003c\/strong\u003e Pre-washed; a quick rinse is optional to clear transit dust.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Chemistry:\u003c\/strong\u003e Calcareous, may raise pH and hardness over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety:\u003c\/strong\u003e Safe for fish, shrimp, and plants when used as directed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile:\u003c\/strong\u003e Ideal for aquariums, paludariums, and terrariums.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Boulder Boxes, \u003cstrong\u003eNano\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e5 kg (≤45 cm tanks),\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eBox\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e11 kg (≤60 cm),\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eMega\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e21 kg (≤90 cm).
