WIO Hole Stone Kit is a one-of-a-kind hardscape element defined by its remarkable natural perforations — distinctive holes of varying sizes that perforate the stone's warm, gritty surface. These openings are not just visually striking; they create functional caves and shelters for aquatic animals, and provide perfect anchoring points for epiphytic plants and mosses, making Hole Stone as practical as it is beautiful.

The warm coloration and highly textured surface of Hole Stone add a natural and artistic touch to any aquarium or vivarium. The irregular holes give each piece a unique sculptural quality, creating depth and dimension that draws the eye and rewards close inspection. Whether used as a dramatic focal point or incorporated throughout a layout, Hole Stone adds instant character and a sense of ancient, eroded geology to any scape.

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