Meridian is an all natural oolitic (spherical or egg shaped) aragonite substrate for all reef and marine aquaria. Meridian is the premium aragonite substrate for the reef aquaria.

Unlike competing "wet" products marketed under the guise of being "live", Meridian is sold dry, thus you pay only for gravel and not for unneeded water. These products imply that they contain living, microscopic animals when in fact they only contain common bacteria. Dry or wet, there are bacteria on every substrate available.
