Create a mature-looking reef aquascape without harvesting rock from natural reefs. CaribSea LifeRock is made from an aragonitic base material with realistic textures, natural-looking shapes and a purple coating designed to resemble established coralline algae.

Its porous internal structure provides extensive surface area for beneficial bacteria, helping support biological filtration in saltwater aquariums. LifeRock arrives dry, requires no curing and can be used to build caves, ledges, arches and other custom aquascapes.
