    Silver-grey Onyx gravel is a porous substrate suited for freshwater, marine or, ideally, cichlid aquaria. Onyx Gravel is not chemically coated or treated, but does have a slight buffering capacity.

    The size and color of the gravel and substrates listed can vary due to natural availability and the resolution of your computer monitor.

    For help selecting how much gravel you need for your aquarium, check our Aquarium Substrate Buying Guide.

    Although pre-washed, it may be rinsed before use to remove residual dust. Dust can also be minimized by filling aquarium slowly and dispersing water so that the Flourite bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours). To shorten the cloudiness period use Seachem Clarity in conjuction with mechanical filtration (such as filter floss).

    I purchased this 1 bag of Onyx gravel and mixed in with 1 bag of the Onyx sand for my 29 gallon starter aquarium for cichlids. I rinsed in thoroughly and it looks fantastic in the aquarium. I mixed the two substrates to provide a unique consistency for the cichlids at it is working out great. The only downside which I didn't mind was that it did require quite a bit of rinsing but the end result was what I was looking for.
