Grey River Slate is a layered sedimentary stone shaped naturally by water erosion in riverbeds. Its smooth surfaces and flat shapes make it a versatile choice for layered scapes, terraced aquascapes, and naturalistic layouts. With its subtle gray tones and clean lines, Grey River Slate adds calmness and structure, making it ideal for aquarists who want to recreate realistic river terrains.
