Ibon Riverbed – High-Contrast Mountain Stream Substrate

Inspired by the pristine ibons—glacial lakes nestled in the Pyrenees of Spain and France—Ibon Riverbed captures the essence of alpine streams with its striking mix of light sands, dark gravels, and smooth mountain pebbles. This naturally balanced composition brings a crisp, moody ambiance to your aquarium or terrarium, perfect for aquascapers seeking contrast, clarity, and character.

Description

Ibon Riverbed reflects the rugged yet serene landscapes of high-altitude mountain rivers, where water sculpts stone into smooth, cool forms and deposits layers of sand and gravel along stream beds. The interplay of light-toned sands with dark pebbles and gravels creates a bold visual contrast that amplifies plant greenery and highlights aquatic life—while evoking the mysterious stillness of alpine water.

Crafted from 100% natural and non-toxic materials, this substrate is as safe as it is beautiful. Though it may slightly influence water hardness, it remains easy to manipulate and shape—making it suitable for hobbyists of all experience levels.

Whether you're recreating a Pyrenean biotope or simply looking to introduce contrast and depth to your layout, Ibon Riverbed provides a ready-made canvas for stunning scapes.
