ADA KUMU Flat River Gravel - Small

250 ml - 5–10 mm

The ADA KUMU Flat River Gravel S is a natural hardscape gravel from the KUMU Layout Materials series, featuring smooth, flat stones in subtle earth tones. Its gentle colour palette and low‑profile shape make it an excellent choice for planted aquarium foregrounds, terrariums, and paludariums, where fine texture and natural flow are key to creating cohesive layouts.

With a size range of 6–10 mm, this gravel works perfectly for adding detail in the foreground or midground, defining pathways, and establishing gentle transitions between substrate zones and larger hardscape elements. The flat surfaces create calm visual planes that support both carpeting plants and driftwood accents while maintaining balance and scale within the design.

Water Parameters

Flat River Gravel S is generally stable and has minimal impact on water chemistry, making it suitable for most freshwater planted aquariums and community setups. Minor mineral contributions are possible, but will not significantly affect water stability in a well‑maintained system.

Versatile by Design

Beyond aquarium use, ADA KUMU Flat River Gravel S enhances terrarium and paludarium layouts with its natural texture and adaptable size. Whether used to accent hardscape transitions, define foreground texture, or create structured midground features, this gravel adds a subtle and nature‑inspired foundation to your composition.
