Seachem Onyx Gravel 7kg (SC-3705)
Seachem Onyx is a natural substrate ideal for Cichlid aquarium. The carbonate-rich gravel can serve as a stand-alone substrate bed, or mixed with other sand, for marine and freshwater applications. Seachem Onyx is a permanent substrate for your aquarium. It does not deplete, hence no replacement is necessary.
Advantages
Gravel is one of the most important elements of an aquarium. The gravel serves as a home for beneficial bacteria. As bacterial colonise the substrate, natural bio filtration takes place within the substrate as the bacteria breaks down organic wastes, leftover food, and plant debris. This helps to keep the water clean and safe for your fish and plants.
Onyx is a specially fracted natural substrate for the aquarium. Onyx 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. Onyx is not chemically coated or treated but does have a slight buffering capacity.
Set-up
Although it is pre-washed, because Onyx 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 Onyx 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. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity to accelerate clearing.
