CaribSea Life Rock 40 lb Box

LifeRock™ Don’t just put rocks in your tank, ROCK YOUR REEF with LifeRock™. Amazing porosity, incredible biological performance (drops ammonia like real live rock), and unsurpassed realism make LifeRock™ the best and most cost effective rock choice for any aquarist. 

So real, so ready. Are you?

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.
