[edit] Marine: A Definition

Marine is defined "of or pertaining to the ocean or sea," while saltwater is more narrowly defined by aquarists.

The classification of different waters by their salt content, as measured by Specific Gravity (relative density) is:

  • Marine or Saltwater 1.022 – 1.035
  • Brackishwater 1.05 – 1.010
  • Freshwater 1.0

[edit] Specific Gravity of Different Marine Regions

  • Tropical Indo-Pacific 1.022 – 1.025
  • Caribbean 1.023 – 1.026
  • Red Sea 1.028 – 1.035
