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.

Every box of Shapes LifeRock contains a mixture of arches, rings, and tunnels giving you unique looking pieces that can be used on their own or as accents to the rest of the aquascape.
