CaribSea Life Rock 40lb 18.2kg

It is safe for all fish and inverts, and is an aragonitic base material (does not contain cement), requires no curing, and is infused with spored, live bacteria. Once placed in water, the dormant bacteria will come alive and begin to colonize: helping to speed up the cycling process.

CaribSea Life Rock is colored to simulate real coralline algae so you don`t have to wait 6-8 months for coralline algae to grow to have a mature-looking tank. 

We recommend 1 to 2 lbs. of rock per gallon of aquarium water. 1 pound per gallon for a open-water landscape with more space for your fish to swim. 2 pounds per gallon for a denser landscape so you can create more caves/crevices and more area to place your corals.
