I used this substrate for my Zen-style aquarium and it brings a calm, traditional feel. The color is subtle and realistic, and the pebbles hold their shape well over time.

Great for creating a natural look in a rock garden setup. The silver tones blend well with the stones. A bit coarse for very delicate plants, but ideal for most aquascaping styles.
