Hakkai Stone, also known as Pa-Hai Stone or Bug Eaten Stone, is a best selling aquarium stone! It’s easy to spot thanks to its signature mix of blue, grey and subtle green undertones. Combine this with its smooth, rounded shape and naturally eroded grooves, Hakkai is an absolute gem for aquascaping! Its unique features and soft color are the result of years of natural weathering, which also contributes to its rarity and limited availability when compared to other popular stones used for planted aquariums.

On the density scale, it is one of the heaviest used in the hobby. If you've checked out our general calculation for how many pounds you need for your planted tank, we recommend ordering extra, if possible, to receive multiple pieces and a wider variety of sizes. It is also inert, making it a safe choice that won’t alter parameters. If you enjoy river-style aquascapes, Iwagumi layouts or calming nature aquariums, Hakkai Stone will be the first stone we recommend. Pair it with delicate or grass-like aquatic plants to complete the look.
