## Description

Product Description          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. 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)             Directions          Simply rinse before use to remove any residual dust. When adding water to aquarium, fill slowly to avoid disturbing GrayCoast™ substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity™ to accelerate clearing.
