Caribsea CoralineCORALine™

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!

This product is ideal where flow rates are important, such as deep beds, reverse flow, and trickle through filtration. An ideal platform for water purifying bacteria plus provides pH support and calcium input. Excellent media for many commercial applications such as lobster holding facilities, shark tanks, etc.

Liferock

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.
