KUMU GR-02 Flat River Gravel 250 mL

KUMU GR-02 Flat River Gravel (250 mL) — SKU 106-722

Larger flat river gravel with the same natural character as GR-01 S. The increased grain size (10–40 mm) makes this gravel ideal for bolder accents, midground features, or creating depth perception in layouts.

Key Characteristics:

• Color: Mixed gray, tan, and brown tones (same palette as GR-01 S)
• Grain Size: 10–40 mm (larger mixed pieces)
• Shape: Flat, water-worn edges
• Volume: 250 mL per pack

Aquascaping Applications:

• Midground Accents: Use larger gravel pieces as focal points or to frame hardscape
• Depth Perspective: Place larger pieces in the foreground, transitioning to smaller pieces (GR-01 S) in the background to enhance depth illusion
• Paludarium Shorelines: Scatter along the water's edge to simulate a naturalistic stream bank

Planting Strategy:

• Use GR-02 around the base of large stones or driftwood to create transition zones
• Combine with GR-01 S for multi-scale realism (large gravel in foreground, small in background)

Setup Tips:

2. Apply over base substrate in targeted areas

3. Use tweezers or your fingers to position larger pieces precisely

Maintenance:

• Larger gravel is easier to clean than fine gravel—detritus is more visible and easier to siphon

Why Use GR-01 S & GR-02 Together?

Combining small and large Flat River Gravel creates a more realistic stream bed. In nature, flowing water sorts gravel by size—using both sizes mimics this natural sorting and adds depth to your layout.

Key Features:

• Designed for long-lasting performance and reliability
• Maintains the pristine aesthetic of your aquatic display
• Easy to install and integrate with existing equipment
