Marsh Stone is a weathered volcanic rock shaped by natural processes in swampy, boggy environments. Its rounded surfaces and organic textures make it ideal for naturalistic biotope aquascapes and blackwater setups, where subtle, earthy character is key. Slightly altering water chemistry, Marsh Stone brings a wild and natural authenticity to aquariums.
