You can now bring the world's most exotic reefs into your home with CaribSea's Arag-Alive substrates. They are developed from CaribSea's cooperation with public aquariums and zoological parks, where authenticity is a must.
Arag-Alve line of live sands achieves rapid cycling by first preparing, and then seeding the aragonite grain surfaces with spored marine bacteria for maximum longevity and thermal resistance. These bacteria strains are specifically engineered for maximum waste reduction. Some types of bacteria reduce nitrogenous waste by metabolic oxidation while others incorporate nitrogen into bacterial biomass during the rapid growth phase. Bacteria are maintained in a spored state before introduction into an aquarium by restricting access to certain limiting factors required for active metabolism. When Arag-Alive is introduced into a new aquarium, the bacteria are activated, compressing or eliminating the ammonia cycle.
While some fishes that live over sand flats and slopes near coral reefs construct a burrow to live in, others seek shelter in and may actually "swim" under the substrate. Many wrasse species will dive under a fine substrate surface when they feel they are in danger. In these species, a fine substrate with a small, relatively homogenous grain size can ensure that they will not damage themselves when engaging in "sand diving" behavior.
Hawaiian Black Sand: Many sand slopes around the volcanic islands of Indonesia are comprised of black sand. The colors of substrate-bound fishes that live in thse areas are often impacted by the pulverized lava sediments they live on. These fishes regularly sport darker or more intense colors than their cousins that live on lighter sand bottoms. You can recreate the appearance of this unique habitat with CaribSeas's Hawaiian Black substrate.
