Olibetta Hakkai Stones, 60 (1 carton)

Hakkai Stones have rounded shapes, subtle colours and a weathered surface. They are ideal for recreating peaceful riverbanks and natural mountain scenery without changing your aquarium's water parameters.

Product highlights:

• Subtle colours: Muted grey, brown and earthy shades create a calm, balanced look.
• Weathered surface: Irregular grooves and small hollows give every stone its own character.
• Rounded shapes: Soft outlines make it easy to arrange balanced rock groups and gentle transitions into the substrate.
• No effect on water chemistry: The rocks do not release substances into the water or increase its hardness.
• Easy to combine: Pair with pale sand, fine gravel, aquarium wood and lush green plants.

Set contents:

• 60: 8 stones (6 M, 2 L)
• 80: 10 stones (7 M, 3 L)
• 100: 14 stones (9 M, 4 L, 1 XL)
• 120: 18 stones (11 M, 5 L, 2 XL)

How to use:

• Use larger stones as focal points and arrange smaller pieces around them to create balanced groups that blend into the substrate.
• Add mosses or plants such as Anubias, Bucephalandra or Java fern between the stones to soften the transition from hardscape to planting.

A closer look:

Hakkai Stones are well suited to natural-looking riverbanks and mountain landscapes. Their gently rounded shapes and weathered surfaces feature small grooves and hollows that give them the appearance of rocks worn over time. The grey and brown shades deepen underwater, bringing out the texture and adding depth to the layout.

The understated colours sit comfortably among aquarium plants. Pale sand or fine gravel, aquarium wood and rich green foliage complete the scene. As the rocks do not alter water parameters or increase hardness, you can use them without changing the water chemistry of your aquascape.
