WIO Nano Rocks - Etna Lava*

Etna Lava Nano Rock is the compact expression of WIO's multicolored Etna Lava line — a volcanic rock with deep brownish-red, maroon, and dark burgundy tones and highly porous, bubbled texture, scaled perfectly for nano tanks. Its rich, dark volcanic palette and porous surface make it an ideal support for mosses and epiphytic plants in any small-scale composition.

Etna Lava Nano Rock carries the same dense, highly textured character as the full-size stone, with a richer, darker coloration than Wild Red Lava. Sized between 3 and 10 cm, perfectly suited for nano tanks under 40L. Fully inert — does not affect water hardness.
