What are the benefits of this gravel?

The 1-2 mm grit size benefits the tank as it offers an optimal settlement area for the useful cleaning bacteria. The gravel will not change the water values due to it being hardness-free and water-neutral.

Due to its round edges it will make a perfect addition to any tank with any bottom feeders such as catfish as their sensitive barbels will not be injured.
