WIO Grey Fossil Stone Kit is a unique metallic grey stone characterized by its monolithic forms and sophisticated rounded shapes. It is often mistaken for Fossil Wood due to its similar shape and texture, but it is actually a highly metamorphic rock that contains bands, layers, or lenses of blocky crystals such as feldspar, alternated with bands of a flat, plate-like mineral such as mica. Gneiss represents some of the most advanced stages of metamorphosis with some of the most intense temperatures and pressures.

Grey Fossil Stone is an excellent stone for scaping, especially in creating layouts with a great sense of depth and high impact. The stone's different heights and thicknesses allow for easy paths and complex rock formations. Its glittering, metallic surface creates a remarkable contrast with plants and opens up exceptional possibilities for aquascaping enthusiasts.

Grey Fossil Stone may slightly raise pH and water hardness; regular water changes are enough to keep hardness under control.
