{"product_id":"wio-stone-ryuoh-seiryu","title":"WIO Stone - Ryuoh(Seiryu)","description":"\u003cp\u003eRyuoh is the language of mountains — jagged faces, deep cuts, and pale mineral veins that read like storm-split cliffs. Place a single ridge and the scape sharpens; compose a range and you get instant altitude, with silhouettes that photograph beautifully and hold attention from across the room. Under water the greys darken and the veins glow; in dry scapes the surfaces mattify into a cool, sculptural calm.\u003c\/p\u003e\n\u003cp\u003eLet the ridgelines set the rhythm. Seat the tallest piece slightly off-axis to establish motion, then echo its fracture angles with supporting stones to create saddles, spurs, and natural fall lines where \"water would move.\" Keep negative corridors between masses so the scene breathes. Half-bury a few fragments to mimic talus — small choices that make the layout feel discovered, not arranged.\u003c\/p\u003e\n\u003cp\u003eRyuoh loves expressive lighting. Raking side light carves razor highlights along edges while clefts hold shadow for depth; soft top light turns the whole composition into a highland mist. Pair with pale sands like Heaven for crisp, classic Iwagumi contrast, or use a darker bed to deepen the drama. Driftwood adds organic counter-lines; fine-leaf plants and moss soften tension without diluting structure. Veil bases with \u003cstrong\u003eWIO Accents Grey Chips\u003c\/strong\u003e so cliff faces step naturally into scree and foreground.\u003c\/p\u003e\n\u003cp\u003eAs a calcareous limestone, Ryuoh can gently lift pH and hardness over time — part of its authentic mineral signature. Simple routine water changes or buffering keep parameters steady while the stone's mountain character anchors the layout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Points\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eJagged grey limestone with pale mineral veins — iconic Iwagumi stone\u003c\/li\u003e\n\u003cli\u003eDeep cuts and fractured planes catch directional light dramatically\u003c\/li\u003e\n\u003cli\u003eIdeal for Iwagumi, mountain, and cliff-style aquascapes\u003c\/li\u003e\n\u003cli\u003ePairs with WIO Accents Grey Chips and pale sands (Heaven)\u003c\/li\u003e\n\u003cli\u003eCalcareous — may gently raise pH and hardness over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCharacteristics\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Calcareous limestone\u003c\/li\u003e\n\u003cli\u003eColor: Grey with pale white mineral veins\u003c\/li\u003e\n\u003cli\u003eTexture: Jagged, fractured faces with deep cuts and ridgelines\u003c\/li\u003e\n\u003cli\u003eStone size: Mix sizes from 5 to 30 cm\u003c\/li\u003e\n\u003cli\u003eWater Hardness: Calcareous — may gently raise pH and hardness over time; regular water changes maintain stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability at Cuboid Nature Aquarium\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNano Box — 5 kg (11 lb):\u003c\/strong\u003e WIO's curated size mix, hand-selected assortment of stones from 5 to 30 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox — 11 kg (24 lb):\u003c\/strong\u003e WIO's curated size mix, hand-selected assortment of stones from 5 to 30 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn-Store:\u003c\/strong\u003e Visit us in Pipersville, PA to hand-pick individual stones by the pound — choose exactly the pieces and sizes you want for your layout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUsage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuitable for both aquatic and terrarium environments\u003c\/li\u003e\n\u003cli\u003eRinse rocks and stones with water before use; use a brush to clean before introducing to the aquarium\u003c\/li\u003e\n\u003cli\u003eAvoid placing rocks directly on the glass — place substrate or WIO LandForms beneath the hardscape first\u003c\/li\u003e\n\u003cli\u003eAlways secure stones, especially when stacking; use WIO ScapeBound to prevent movement during maintenance\u003c\/li\u003e\n\u003cli\u003ePosition stones a few centimeters\/inches away from aquarium glass walls to facilitate maintenance\u003c\/li\u003e\n\u003cli\u003eControl any alterations in pH and kH by regular water changes with osmotic or soft water, or by using a water softener if necessary\u003c\/li\u003e\n\u003cli\u003eSafe for fish, shrimps, and other aquatic animals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eAvailable from Cuboid Nature Aquarium — Authorized Retailer for WIO.\u003c\/em\u003e\u003c\/p\u003e","brand":"WIO","offers":[{"title":"5kg(11lb)","offer_id":51218825675063,"sku":"52965","price":35.0,"currency_code":"USD","in_stock":true},{"title":"11kg(24lb)","offer_id":51218793398583,"sku":"52966","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/8748\/1655\/files\/5f6902_1fa60ba3894341b285097e987bee0840_mv2.avif?v=1760573505","url":"https:\/\/cuboidstore.com\/products\/wio-stone-ryuoh-seiryu","provider":"Cuboid Aquatics LLC","version":"1.0","type":"link"}
