WIO - Stream Gravel

Stream Gravel – Your Ready-to-Scape Riverbed Substrate

Stream Gravel is a natural grey-toned gravel designed to recreate the rugged character of high mountain streams. With its slightly rough texture and varied stone sizes, it brings depth, realism, and authentic flow to aquascapes, terrariums, and biotope displays. Each stone is naturally rounded and river-worn, offering a timeless, nature-true foundation for your layout.

Perfect for cold-water themes, alpine-inspired scapes, or as an accent layer in planted tanks, Stream Gravel adds structural detail without overpowering your hardscape. Its curated mix of sizes makes it easy to craft natural gradients, slopes, and riverbed transitions straight from nature.
