Aqua Natural Iwagumi Colorado Substrate Sand 3.5kg

Achieve the serene balance of premium Japanese aquascaping with Aqua Natural Iwagumi Colorado Substrate Sand. Specially selected by master designers for high-end Oliver Knott and traditional Zen-style layouts, this cosmetic sand features an exquisite palette of crisp white and soft, earthy undertones. It creates a striking visual contrast when placed against dark volcanic rock, dragon stone, or vibrant green carpeting plants.

Engineered with a fine 0.5–1mm uniform grain size, this 100% natural and sustainable substrate offers a smooth texture perfect for showcasing intricate hardscape details. Its dense, triple-washed formulation ensures excellent placement stability around structural focal points like the Oyaishi (main stone) without shifting under filter currents. It is entirely inert, non-toxic, and safe for delicate freshwater fish, bottom-dwelling scavengers, and sensitive dwarf shrimp.
