Black Mountain Seiryu Stone is a wonderful stone commonly used for aquascaping. Similar to its popular relative, Seiryu Stone, Black Mountain Seiryu earns its name due to its charcoal grey, almost black color with blueish undertones. Black Mountain Seiryu Stone also offers similar texture and characteristics such as grooves, interesting shapes, and more making it a good pair when using brightly colored aquarium plants. Application is very versatile and like normal Seiryu, Black Mountain Seiryu works wonderfully alone or paired with aquarium driftwood in planted aquarium tanks.

Seiryu rocks and customer service

"Glass Aqua has a well deserved reputation as a great resource. My rocks were selected with the good taste of experienced aquascapers. The site photos are helpful to a beginner like me. During an earlier mistaken order by me, they reacted fast and professionally. Plants were health and well packed. Now to actually produce a scape vs algae. 🙏"
