Black Mountain Seiryu Stone

Black Mountain Seiryu is the darker cousin of the well known Seiryu stone. We personally like the darker grey, almost blueish tone that it has compared to regular light grey Seiryu. The craggy texture and endless details in these stones allow you to easily create a natural looking aquascape.  

Seiryu may slightly raise pH and water hardness. Controsoil can help balance that out. 

Pieces from packages will range from 3-10 inches.

If you are looking for larger stones, a minimum weight may be required. Larger stones = higher weight. Email our team if you need assistance!

*Stones require rinsing prior to use
