Natural oolitic aragonite sand for all types of marine, reef, and tropical aquaria
Assists in stabilising calcium and alkalinity
Helps prevent large pH declines
Pure dry sand (no water fillers)

Seachem Meridian is natural, oolitic aragonite sand for marine reef aquaria. The oceanic substrate helps to stabilise calcium and alkalinity in your aquarium, and prevents large pH declines.

Advantages
Seachem Meridian is all natural oolitic (spherical or egg shaped) aragonite sand ideal as substrate for all reef and marine aquaria.

Its spherical grain size (a fairly uniform 0.25 – 0.50 mm) makes the sand particularly suitable for reef organisms, while its chemical composition helps to stabilise calcium and alkalinity, thereby preventing large pH declines.

Dry vs Wet Gravels
Unlike competing wet gravels, each bag of Seachem Meridian contains pure sand 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
Seachem Meridian sand is a natural product. Simply rinse before use to remove any residual dust.

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.
