Ocean Max Fine Red River Gravel 1–2mm

Ocean Max Fine Red River Gravel 12mm is a decorative aquarium substrate designed to give tanks a warm red-brown natural look while still being safe for freshwater fish and plants.

What it is

This substrate is:

• Natural-style crushed gravel (not loose sand)
• Grain size: 12 mm (fine gravel)
• Colour: red / rust / river-stone tones
• Designed to mimic natural riverbeds

It's part of Ocean Max's "river gravel" range, which focuses on realistic natural aquascaping looks.

Key benefits

• Natural warm colour gives a reddish riverbed or earthy African stream look
• Fish-safe texture smooth enough for bottom dwellers like corydoras and loaches
• Good for planted tanks roots can anchor easily in 12 mm gravel
• Easy to maintain easier to vacuum than sand
• Good water flow doesn't compact as much as fine sand

Things to watch out for

• Small gaps can trap debris needs regular siphoning
• Red colour may fade slightly over time depending on coating/mineral type
• Not as soft as sand for very sensitive bottom fish
• May slightly affect pH in some setups (usually minimal in aquarium-grade gravel)

Where it works best

• Natural-style aquascapes (river/stream theme)
• Community freshwater tanks
• African cichlid-inspired tanks (for colour contrast)
• Tanks with driftwood + green plants (nice contrast with red gravel)

Simple comparison

• Sand (0.11mm): softer, best for delicate bottom fish
• 12mm red river gravel: balanced look + easier cleaning
• 36mm gravel: more flow, less plant-friendly but very low compaction risk
