Enhance your finned friends’ underwater habitat with CaribSea Coraline Florida Crushed Coral Marine Gravel. This natural, dramatic color and textured marine aquarium gravel is great for brackish or Cichlid aquariums (Central American or African). Because of its coarser material, Florida Crushed Coral is suitable for most under-gravel filtration and fish systems or as an accent for finer sands wherever elevated pH values are needed. Since it’s extremely porous, it aids in the filtering process by increasing the surface area available for nitrifying bacteria to colonize. The non-toxic coral is approximately 2.5-5.5 mm in size, plus it helps support alkalinity. In addition to saltwater tanks, this crushed aquarium coral is also ideally suited for adding beauty to terrariums, potted plants, vases, and much more—just make sure to use 1-2 pounds per gallon for best results.
