Onyx Sand is not chemically coated or treated, but does have a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units. This premium substrate will last the life of your aquarium and never needs replacement. It is pre-washed, but should be rinsed prior to use to remove any residual dust particles. Slight initial cloudiness is to be expected, but will clear with 12 hours.
