You can now bring the world’s most exotic reefs into your home with CaribSea’s Arag-Alive! substrates. Eight environmentally accurate ecoscapes, developed through CaribSea’s cooperation with public aquariums and zoological parks where authenticity is a must, Arag-Alive! makes any aquarium uniquely yours. Arag-Alive! makes it easy to set up an aquarium. It’s ready to work, clears quickly, and contains millions of live bacteria to cycle super fast and create a natural biological balance. Arag-Alive! suppresses the dreaded “new tank syndrome”, compresses the ammonia cycle, and discourages nuisance algae. In fact, independent labs prove Arag-Alive! cycles days faster than other brands of live sand. That’s what makes Arag-Alive! the choice of new aquarists and maintenance companies where speed of set up, beauty, and reliability are demanded.
