Purple Life Rock - Base Rock - 40 Lbs - CaribSea

Build the perfect foundation for your reef with the LifeRock Base Rock 40 lb Box. Designed for structural support and natural aesthetics, this base rock features rugged, irregular shapes ideal for stacking, anchoring coral placements, and creating a stable framework for your aquascape.

Each box contains 40 pounds of aragonitic base rock, infused with spored bacteria to help kickstart your tank’s biological filtration—no curing required. The rock’s high porosity provides ample surface area for beneficial nitrifying bacteria, while the coralline-style coating delivers a mature reef appearance straight out of the box.

Rock is naturally fragile and some breakage may occur during shipping. While we inspect and securely pack each box, carrier handling is beyond our control. Shipping insurance does not cover breakage, so we cannot offer replacements.
