Hakkai Accent Stones

Hakkai Stone, also known as Pa-Hai Stone, is a rare and popular aquascaping stone. Coveted for its unique characteristics, Hakkai Stone is unlike any other aquascaping stone available. Hakkai Stone displays a mixture of blue, grey and green-ish hues in-tank and sports a smooth, rounded shape with natural grooves earning its alternative name, Bug Eaten Stone. This aquascaping stone is highly coveted and falls on the rare side as its characteristics are the result from years of natural erosion making availability limited when compared to other aquascaping stone choices. On the density scale, Hakkai is one of the heaviest stones available on the market, increasing its rarity further. If you enjoy river scapes, river-style planted aquariums or Iwagumi layouts, Hakkai Stone is a top contender! We recommend pairing this stone with delicate aquarium plant species or grass-like aquatic plants for a calm, scenic planted aquarium.

Please note the provided calculation is a standard rule of thumb. Hakkai Stone is very dense and will weigh more when compared to other stone choices. We recommend increasing the amount ordered, if possible, to receive a multiple stones and/or a larger variety of sizes.

TIP 1: Use Hakkai aquarium stone for creating unique riverscapes and pairing it with softer, wispy aquatic plant choices such as Dwarf Hair Grass, Utricularia Graminifolia, Blyxa Japonica, Potamogeton Gayi and more.
