【Pure Natural and Dark Color】Black lava is of volcanic origin and is rich in minerals and trace elements. It remains in its original state, except for being hand-picked and cleaned. It has a very dark color, a rough surface and a porous texture. Due to its comparably low weight, it is possible to create large structures with it.
【Diverse Types of Landscaping】Black Lava Rock is an essential aquascaping stone that’s often used in all types of aquarium setups. It can be used alone or combined to create landscapes such as caves, cliffs, and mountains. In addition to direct use, it can also be crushed and used as a bottom, which facilitates the growth of plant roots.
【Suitable with Aquatic Plants and Ferns】Black lava is often paired with epiphytic aquatic plants and aquatic or terrestrial mosses. Simple aquatic plants find root footholds on stones easily and self-attach rather quickly. Moss-covered rocks can form a forest scene.
【Porous Structure for Bacteria Cultivation and Water Purification】The porous texture of lava rock creates a good habitat for the survival and development of beneficial bacteria such as nitrifying bacteria, making the aquarium environment healthier. The rough surface also has a filtering function that absorbs harmful bacteria, debris, feces and harmful heavy metal ions, keeping the water in the tank clean.
【Stable Nature and Activated Water】Lava stone is stable in nature, so it does not affect the composition of the aquarium and increase the hardness of the water, and it helps to stabilize the PH value and mineral content. It also promotes the activity of oxygen ions in the water, which helps the metabolism of plants and animals in the aquarium.
Customers say
Customers find these dragon stones excellent for aquascaping, particularly for frontosa aquariums, and appreciate their various sizes, with one customer noting they’re suitable for different aquascapes. The rocks receive positive feedback for their appearance, with one mentioning how they shimmer in light, and customers consider them worth the price. However, the dirt content receives mixed reviews – while some customers report minimal dust, others mention the stones are covered in dirt and pill bugs.

Great quality
Good amount of rocks for the price and nice quality, identical to photos. Came nicely packaged and adapted quickly to my tank. Highly recommend for larger tanks (20 gallons and up) due to the large proportions of the rocks and amount of rocks you get ð

Brandon Dement –
Extremely high quality, exceeded expectations, great price
These are EXACTLY what I was hoping for. No skimping in the quality and size of these stones. I will definitely look to buy more hardscaping products from this seller

Maple Leaf Stones
Received the package on time and everything was well packaged and individually wrapped. Seller even includes information on the rocks in the package. Only reason I didnât leave a perfect 5 Iâd one of the larger stones was largely covered in an unattractive mineral (or other stone material?). None of the other stones in the package had this issue.

Quality hardscape
Excellent group of lava stones. Buying something like rocks for hardscape sight-unseen is a gamble to be sure, but I was very pleased with both the selection of stones I received and how quickly I received them.

These were actually fantastic. They were far prettier in person with good size variety. It was a total gamble ordering this but if I ever need more I’ll definitely order another box of these.
Themarkman –
Pretty good for a little extra money compared to some others on Amazon. Wish there could have been a bigger piece but thatâs what super glue is for! Febreze bottle for scale.The stone is dense as well and not comprised of small stones held together by clay (like some dragon stone Iâve bought). All in all- solid purchase.
Mark T. –
Pleasantly surprised. Beautiful rocks. I’d say they weigh what feels like more than 17 lbs but I don’t have a scale to weigh. Each rock came wrapped individually in paper.
SFCT –
I really like those stones.I received less (but larger) stones than what I expected from the pictures, however, it’s something the company mentions in their description, so at the end I’m very happy.It’s been a while now and the stones are still there and fit the landscape really well.
