![]() You can recreate the appearance of this unique habitat with CaribSeas’s Hawaiian Black substrate. These fishes regularly sport darker or more intense colors than their cousins that live on lighter sand bottoms. The colors of substrate-bound fishes that live in thse areas are often impacted by the pulverized lava sediments they live on. Helps buffer and maintain pH levels to 8.2. Small grain size provides larger surface area for the growth of beneficial bacteria and a more efficient live sand bed. Hawaiian Black Sand: Many sand slopes around the volcanic islands of Indonesia are comprised of black sand. Arag-Alive Bahamas Oolite sand has an approx grain size of 0.25-1 mm. 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. Many wrasse species will dive under a fine substrate surface when they feel they are in danger. 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. When Arag-Alive is introduced into a new aquarium, the bacteria are activated, compressing or eliminating the ammonia cycle. Bacteria are maintained in a spored state before introduction into an aquarium by restricting access to certain limiting factors required for active metabolism. ![]() Depositional Setting of the Miami Oolite. Some types of bacteria reduce nitrogenous waste by metabolic oxidation while others incorporate nitrogen into bacterial biomass during the rapid growth phase. The Miami oolite serves as a key reference example for comparison to Holocene sand units in the Bahamas, and more importantly, subsurface examples in the geologic record. These bacteria strains are specifically engineered for maximum waste reduction. ♼reates a natural biological balance to discourage nuisance algae growthĪrag-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.
