The ideal substrate for marine, reef or African Cichlids. Ideal for deep beds, plenum systems, reef or fish tank bottom cover.

  • Removes nitrate, nitrite, ammonia and other wastes.

  • Maximum surface area -- up to 10,000 square inches of surface area per cubic inch.
  • High uniformity coefficient prevents biofouling.
  • Supports the proper pH of seawater (8.2) with the fastest reaction time.
  • Precision grading and enhanced internal surface area allows CaribSea Aragonite to deliver more calcium, carbonate buffer and essential trace elements than any other substrate.
  • Creates a natural biological balance to discourage nuisance algae growth.
  • Available in the ideal grain sizes (approximately 1-2 mm) for reef tanks, fish aquarium, plenum systems and refugiums.
  • Pure aragonite -- no tar, harmful organics or impurities.
