Seachem Gray Coast 3.5kg (SC-3623)
Gray Coast Calcite is an all natural calcite substrate for all types of marine, reef and tropical aquaria. It helps to stabilise calcium and alkalinity while preventing large pH declines.
Advantages
Gray Coast is a natural calcite substrate for marine, reef and tropical aquaria. It helps to stabilise calcium and alkalinity while preventing large pH declines. It comes dry without any fillers and contains beneficial bacteria that promotes bio filtration. Simply rinse before use.
Dry vs Wet Gravels
Unlike competing wet gravels, each bag of Seachem Gray Coast contains pure gravel without water as filler.
Some wet gravels are marketed as containing living, microscopic animals when in fact they only contain common bacteria.
Dry or wet, bacteria exists naturally in 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 Stability).

Set-up
Simply rinse the Seachem Gray Coast before use to remove any residual dust.
When adding water to aquarium, fill slowly to avoid disturbing Gray Coast 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.
