This interesting color twist on Samurai Soil makes for a spectacular display! Maroon, black, and white spheres (1 mm approx.) are a beautiful and functional backdrop for shrimp and planted aquaria. Samurai Soil is incredibly porous and pH neutral, and will not disintegrate or turn to mud. The smaller grain size keep smaller shrimp from getting lost in the substrate and increases biological filtration.
