Onyx Sand Aquarium Substrate is a natural, dark gray sand that can enhance the appearance of any aquarium.
It is specifically designed to support optimal KH levels for freshwater planted aquariums. This substrate can be used alone as an integral substrate bed or mixed with other gravels.
It does not require any gravel modifiers such as laterite. Onyx Sand is not chemically coated or treated and has a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units, depending on the source water characteristics.
