Arag-Alive Special Grade Reef Sand 20lb Live Sand
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.
•Contains specially selected strains of live marine bacteria to rapidly cycle your tank
•More than 12,000,000 heterotrophic bacteria per pound
•Unsurpassed buffering capability: keep more fish healthier, longer
• Removes Nitrate, Nitrite, Ammonia, and other wastes
•Maximum surface area, up to 10,000 square inches of surface area per cubic inch

•Creates a natural biological balance to discourage nuisance algae growth
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.
Selecting the right sand: When choosing the right sand for your tank, it is important to keep a few things in mind.
How much flow will be in the tank?
Aquariums with high amounts of water movement will require sand with a larger grain size. Smaller particles can be blown around easily.
What kind of inhabitants will you be keeping?
Many species do require particular types of sand, like gobies, jawfish, and wrasses. Fish and invertebrates that like to burrow or sift through the sand will do best with smaller particle sizes.
Will it be for a refugium or deep sandbed?
Sand that will be used for filtration or refugium, we suggest using smaller particles that will give bacteria more surface area to grow and thrive on.
How much sand do I need?
Below is a table of common tank sizes and how many pounds of Special Grade Sand is required to achieve a certain depth. Results may vary depending on the aquascaping in your tank, overflow styles, and the specific tank manufacturer. We always recommend getting a little extra sand to make sure you have enough on hand when you are filling your tank.
