CaribSea Rock
So real, so ready. Are you also for CaribSea LifeRock? It is safe for all fish and inverts, and is an aragonite base material (contains no cement), requires no curing and is infused with sporulated, live bacteria. Once placed in water, the dormant bacteria will come to life and begin to colonize: helping to speed up the cycling/maturation 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 into a mature looking tank.
