Calcium carbonate derived from oolitic aragonite is biogenic (created by living organisms) and naturally re-occurring. Protect the reef by using this superior and sustainable substrate. Bahamas sand is raw naturally renewable oolitic aragonite sand that is up to 98% pure calcium carbonate.
The grains are OOLITIC (egg-shaped) and smooth. It is tasteless odorless dustless and sustainable. Combined with its near chemical purity size consistency and small grain structure Bahamas aragonite possesses numerous advantages making it a superior source of calcium carbonate.
