Main Features

Grain Size and Behavior in Aquarium

The uniform grain size of Meridian™, ranging from 0.25 to 0.50 mm, is suitable for reef organisms and promotes good water circulation within the substrate. Its chemical composition contributes to the stability of essential parameters over the long term.

Meridian™ is sold dry. You only pay for the mineral substrate, without unnecessary water, while benefiting from a naturally colonizable support for bacteria present in the aquatic environment.

Installation and Filling

Rinse the substrate before use to remove any residual dust.

When filling the aquarium, add water slowly to avoid disturbing the Meridian™ bed. It is recommended to pour water into a container placed in the aquarium so that it gently overflows onto the substrate.

A slight initial cloudiness is normal. It can be removed using mechanical filtration such as filter floss. Using a compatible water clarifier can speed up the clarification process.
