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. It's grain size (a fairly uniform 0.25 - 0.50 mm) is ideally suited to reef inhabitants and it's chemical composition will assist in stabilizing calcium and alkalinity while preventing large pH declines. 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. If one is concerned with shortening the aquarium cycle time for a new system, then the use of a product designed for that particular purpose would be more appropriate (such as Seachem’s Stability®).

Simply rinse before use to remove any residual dust. To determine the number of bags required for your aquarium, please note that each bag (9 kg, 20 lbs) occupies a volume of 5,300 cm3 (320 cu. in.). To determine your desired volume multiply tank width by length by desired depth.
3.5 kg, 9 kg
Wondering how many bags you will need for your project? It's easy to figure out with this gravel calculator. Just enter the length and width of your aquarium along with the desired depth of the substrate and click calculate. Note: The calculator will always round up. For example, you can't purchase 1.3 bags, so it will return 2 bags.
If you plan on varying the depth of your substrate, use an average depth as your desired substrate depth.
