Seachem Meridian

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 its 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).

Set-up

Although it is pre-washed, because Meridian is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.

When adding water to aquarium, fill slowly to avoid disturbing Meridian 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.

Please Note: Argonite is traditionally used in marine tanks. This can be used in a freshwater setup, but will harden the water substantially, so should only be used in hard water setups, e.g. Cichlid / Rift Lake setups.
