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 tank 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
