Unzan Stone’s Background

Unzan Stones became popular in the aquascaping world from the famous aquascaper Takashi Amano. They originate from Japan close to the head of dormant volcanoes where no erosion has occurred yet. Now, Unzan Stones can be found in other parts of the world but usually have small differences in characteristics.

Unzan Stone Description

The Unzan Stone is actually just volcanic rock in its purest form. It is very jagged and textured with plenty of air pockets and craters. One of the unique features of the Unzan is the ability to put in aqua soil in the crevices and grow Wabi-Kusa style plants in it, thus giving you an incredibly natural and zen-like layout.

Unzan Stones are also typically column stones, creating mountain-like pillars within your aquascape. These rocks can tower over your aquascape like skyscrapers in a city, so only a few are really necessary to bring that dull scape to life!

The Greatness of Unzan Stones

So what’s so special about these stones? Unzan Stones are also lava rocks, so they will not change your parameters within the aquascape. They are also becoming extremely popular due to their ability to grow carpet-like aquatic plants and moss within its pockets. Also, it allows the aquascaper to create natural mountainous features that can have an overall striking effect.
