KUMU Stone Collection
KUMU's curated stone selection offers aquascapers access to diverse textures, colors, and formations from around the world. Each stone type has been chosen for its unique characteristics—from the sharp, reef-like ridges of Ryuoh Stone to the smooth, stream-worn surfaces of Jagure Stone. The KUMU collection emphasizes ease of use: stones are sized and sorted to combine naturally, reducing the trial-and-error typically involved in hardscape composition.
KUMU ST-01 Ryuoh Stone (300 g) — SKU 106-701
A cool-toned stone with sharp, pointed features reminiscent of weathered coral reefs or karst limestone formations. Ryuoh Stone's natural angularity and light gray-to-blue coloration create strong structural presence in layouts, making it ideal for dramatic mountain-style (Iwagumi) or rocky outcrop compositions.

Aquascaping Applications:
Chemical Properties:
Ryuoh Stone is largely inert with minimal impact on water chemistry. It does not significantly raise pH or hardness, making it safe for soft-water setups and sensitive species. However, as with all natural stone, test a sample piece in water for 24–48 hours if you're keeping very sensitive fish or plants.
Combining Tips:

Preparation:
2. Optional: Scrub with a stiff brush to clean crevices
3. Boil for 10–15 minutes if you want to sterilize or accelerate water saturation (helps stones sink immediately)
4. Dry or use wet—Ryuoh Stone typically sinks within hours even without boiling

Why KUMU Ryuoh?
The pointed, reef-like character of Ryuoh Stone is difficult to find in generic aquascaping stone. KUMU's selection ensures consistent quality and sizing, so every pack contains pieces that work together seamlessly. The 300 g pack size is ideal for nano tanks (30–40 cm) or for adding accent pieces to larger layouts.
