ARAG-ALIVE!™
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.

CORALINE™
CORALINE™ – Natural dramatic colors and textures combined with pH support characterize our CORALINE™ and Seaflor™ products. These are coarser materials suitable for most undergravel filtration and fish systems or as an accent for finer sands anywhere where elevated pH values are desirable. Consider the CORALINE™ products in brackish or Cichlid aquariums (Central American or African). Seaflor™ Puka Shell substrates are great additions to fine sands in reef tanks where animals make their homes by burrowing in the substrate. Jawfish, blennies and burrowing crustaceans will especially appreciate the extra “construction material.” Our substrates are purposely engineered and free of impurities such as ash, metals, pesticides, and silica; which allows you to create a safe and beautiful environment for your fish and invertebrates. Precision grading makes system design a breeze!

Every grain of Ocean Direct™ is coated with bacteria and encapsulated by capillary action in a thin film of real ocean water. The thin film is open to the atmosphere for unparalleled gas exchange. This results in high counts of natural and beneficial bacteria with no noxious buildup of metabolic by‑products. Ocean Direct™ provides you with a thriving, natural aquarium in minutes!

LifeRock™
LifeRock™ begins as a sunlit piece of Pleistocene era seafloor thriving with living creatures. Over the next 100 millennia and the retreat of the ocean, this ancient piece of seafloor, now well inland, has formed a pure, aragonite-bearing rock. This clean base rock is 97% calcium carbonate with minor and trace elements such as strontium, magnesium, and barium. This base has an amazing 50% void space which will provide residence for billions of water-purifying bacteria. LifeRock™ is infused with bacteria using AragAlive™ technology which results in a reduction of traditional cycling times. Each piece of LifeRock™ has multiple engineered aragonite coatings that not only maintain the extensive macro-and micro- porosity but yield the soft muted colors of a living reef. LifeRock™ is a superior rock of true marine origin without hitchhikers, organics, or algae. No curing is required. With LifeRock™ you will get the look of an established reef from Day 1.
