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.
Setup
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.
Please Note: Aargonite 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.
