Aquael Basalt Gravel 2 - 4 mm[Weight - 10kg]

The Aquael Basalt substrate is a premium, natural option that enhances your aquarium's aesthetic. The stunning black gravel provides striking contrasts thanks to its deep color.
This natural substrate is free from any synthetic additives or coatings, ensuring it maintains a neutral pH level in the water and does not leach harmful substances. With a fine grain size of 2 - 4 mm, it’s perfect for aquariums housing timid fish that favor a darker environment for hiding.
Available in an array of grain sizes and colors, our natural sands and gravels are thoroughly rinsed and devoid of impurities. They come in sturdy 2-kg or 10-kg plastic bags. Rest assured, they will not alter the water parameters in your aquarium (note that this does not apply to dolomite gravel, which is specifically for tanks housing fish native to Lakes Malawi and Tanganyika).
