CaribSea LifeRock Nano Arch is an eco-friendly, reef-safe alternative to traditional live rock, designed specifically for nano marine aquariums. Each arch is seeded with spore-based bacteria to help establish biological filtration while delivering the natural shapes, textures, and colours of real reef rock.
