WIO Nano Rocks - Etna Lava*

WIO Etna Lava Nano Stone brings rich volcanic depth, complex dark coloration, and exceptional porosity to nano scale — a highly textured igneous stone in deep brownish-red, maroon, and dark burgundy tones, perfectly sized for nano compositions seeking dramatic volcanic atmosphere.

Etna Lava Nano Stone carries the same dense, highly porous character as the full-size Etna Lava Stone — a volcanic rock whose bubbled, cratered surface results from rapid lava cooling, creating cavities ideal for beneficial bacteria, epiphytic plant attachment, and moss growth. Its richer, darker coloration compared to Wild Red Lava offers a more complex, dramatic palette that pairs beautifully with deep green plantings and darker substrates.

Sized between 3 and 10 cm, ideal for nano tanks under 40L. Fully inert — does not affect water hardness. Pre-washed and ready to use.
