- Natural oolitic aragonite for all types of marine, reef and tropical aquaria
- Assists in stabilizing calcium and alkalinity
- Helps prevent large pH declines
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 is ideally suited to reef inhabitants and it's 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).
Simply rinse before use to remove any residual dust. To determine the number of bags required for your aquarium, please note that each bag (9kg) occupies a volume of 5,300 cm3. To determine your desired volume multiply tank width by length by desired depth.
TIPS: When adding water to aquarium, fill slowly to avoid disturbing Meridian 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.
