ADA KUMU Flat River Gravel

250ml – 10–40mm

The ADA KUMU Flat River Gravel is a premium natural hardscape material perfect for planted aquariums, aquascape foregrounds, terrariums, and paludariums. Its smooth, flat pebbles in soft earth tones add a natural riverbed aesthetic, enhancing depth, flow, and visual cohesion in nature-style layouts. The muted colours and organic shapes provide subtle contrast against vibrant plants, making it ideal for creating serene pathways and balanced hardscape compositions.

Sized 10–40mm, this gravel is excellent for midground features, gentle slopes, and filling gaps between larger stones. The flat, rounded surfaces allow for easy planting of mosses and small epiphytes while supporting water circulation at the substrate surface, encouraging healthy root growth in your planted setup.

Water Parameters

Flat River Gravel is generally stable and has minimal impact on water chemistry, making it suitable for most planted aquariums, community tanks, and soft water systems. Minor mineral contributions are possible but will not significantly affect water stability in well-maintained aquariums.

Versatile by Design

Beyond aquariums, ADA KUMU Flat River Gravel is perfect for terrariums and paludariums, bringing natural texture and structure to any layout. Whether defining pathways, accenting hardscape transitions, or layering midground zones, this gravel enhances both the visual appeal and ecological function of your aquascape.
