Seachem Onyx Gravel is a specially fracted natural substrate for the aquarium. Onyx Gravel is suitable for any marine or freshwater environments and is ideally suited for Cichlid environments. Onyx is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels or sands such as Onyx Sand. Seachem Onyx Gravel is not chemically coated or treated but does have a slight buffering capacity.

To determine the number of bags required for your aquarium, please note that each 7kg bag of Seachem Onyx Gravel occupies a volume of approximately 7,000cm3.

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

Tips:
When adding water to aquarium, fill slowly to avoid disturbing Onyx 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).

Available Sizes:
