Build a strong, natural foundation for your reef with LifeRock Base Rock, the perfect starting point for any aquascape. Sold by the pound, this rock features rugged, irregular shapes ideal for stacking and supporting coral structures, ledges, and other decorative pieces in your saltwater aquarium.

Each piece of LifeRock Base is made from real aragonitic rock, not cement, and is infused with spored bacteria to help establish biological filtration from day one—no curing required.
