Seachem Onyx Gravel
Onyx™ is a specially fracted porous 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. Onyx™ is not chemically coated or treated but does have a slight buffering capacity.
