Aqua-Slate™ Substrate (Gravel) is natural aquarium grade substrate for display tanks. It is the ultimate choice for cichlid aquariums or other fish that prefer hard, rocky natural substrate.
Because it is naturally mined; it is safe for your aquarium water and fish. It is also because of this reason that no artificial colourants are used and therefore you can rest assured that you will not have potentially harmful chemicals and contaminants seeping into your aquarium water. The colours vary from bluish to brown; dark brown and hues of blue; some are mixed while others are one colour. The choice is yours.
Aqua-Slate™ Substrate has many different uses and can vary depending on the hobbyist. It can also be used in reptilian enclosures, turtle terrariums and under fine gravel to either increase the height of the substrate or allow for the growth of thicker plant roots.
