Niwa-ishi (庭石) – Aqua Soil 250g

Niwa-ishi (庭石) Aqua Soil is a high-quality planted aquarium substrate crafted to support lush, vibrant aquatic plant growth. Inspired by the balance and minimalism of Japanese aquascaping, this aqua soil provides essential nutrients that nourish plant roots while creating a natural, earthy aesthetic.

Its porous granular structure allows for excellent root penetration and beneficial bacteria colonization, helping maintain biological stability in your tank. Niwa-ishi Aqua Soil also assists in slightly lowering pH and softening water, making it ideal for most freshwater planted setups and shrimp tanks.

The natural dark tone enhances the colors of fish and plants, creating depth and contrast in aquascapes. Whether you’re setting up a Nature Aquarium, Dutch-style layout, or a simple planted tank, this substrate forms the perfect foundation.
