What is  Acid Wash Seiryu Stone?

The craggy texture and endless details in these stones allow you to easily create a natural-looking aquascape.  Black Mountain Seiryu Stone has a darker gray and more pronounced veins compared to normal Seiryu, this effect is achieved by acid washing the stones.  We personally like the darker grey, almost blueish tone of the Black mountain Seiryu more compared to regular light grey Seiryu.

Features:

• Unique form and fine textures.
• Colour: Light to dark grey.
• Slight effect on PH and Hardness.
• Often used in Iwagumi aquascaping.

We would suggest using 10KG per 50L. For example, for a 100L tank use 20KG. An average piece weighs approximately 2-3KG. We aim to include a range of sizes and shapes.
