Gray Coast™ Calcite is an all natural calcite substrate for all types of
marine, reef and tropical aquaria. Its chemical composition will assist
in stabilizing calcium and alkalinity while preventing large pH
declines. Simply rinse before use to remove any residual dust. Unlike
competing “wet” gravels, Gray Coast™ is sold dry: this bag contains 35%
more gravel than a bag of wet gravel of equal weight. These “wet”
gravels are marketed to give one the impression that they contain
living, microscopic animals when in fact they only contain common
bacteria. Dry or wet, there are bacteria on every substrate.
