It even has predrilled frag holes for easy placement, so you can set up something incredible in minutes with no cements or glue! Being modular, you can easily separate fighting corals and re-scape as needed, or just change things around for a new look whenever inspiration strikes.

LifeRock is infused with spored bacteria to aid in biological performance, along with millions of micro and macro passage ways CaribSea's LifeRock Dry Rock is perfect for the environmentally friendly aquarist.

  • Creates a mature looking reef instantly
  • 100% safe for all marine animals
  • Unique pieces
  • Environmentally friendly


CaribSea LifeRock is made of an aragonitic base rock, instead of the typical cement used by many other artificial rock creators. Every rock contains a network of micro and macro pores that intertwine within the rocks internal structure creating the perfect environment for natural nitrifying bacteria. LifeRock is manmade and does not affect our natural resources, making it the perfect option for all marine fish, invertebrates, and corals. 


Every LifeRock from CaribSea has an artificial coating and texture that mimics natural coralline algae after being in the ocean for years. Depending on the animals that you have in your aquarium, they may pick at the coating on the rocks which will not harm them at all, and over time live coralline algae will cover any spots on the rocks that may have had the coating picked off.


Shipping: All rock can be fragile. BRS makes every effort to securely pack any type of rock. However, we have no control how UPS handles it and it may break during shipping. Unfortunately, this is not covered by insurance so we are unable to replace broken pieces.

Product Questions

How many pounds of rock is this?
Question by: Melissa on Sep 21, 2022, 7:25 AM
They advertise it is enough rock to build a structure aproximately 22"x22"x22". They dont advertise a weight, but I weighed one in our warehouse and the box full of rocks was aprox. 25lbs. Each box may vary though.
