CaribSea - Samurai Soil 9lb

Samurai Soil - Freshwater Substrate
The ideal substrate for shrimp and planted aquaria. This unique, uniformly graded material (1 mm approx.) fits the pH and mineral requirements of the most sensitive freshwater fauna and flora, without the muddy texture and crumbling often seen with other brands. The smaller grain size keep smaller shrimp from getting lost in the substrate and increases biological filtration.
