of aquarium is well aware that choosing the right substrate will positively influence both the general appearance of your fish tank and the condition of fish and other organisms that you keep in it.
The offered black sand gravel is 100% natural, which can give the grains a slightly brown tinge. The black colour beautifully highlights the colours of fish or shrimp. The gravel does not change the pH value or hardness of the water.
We offer the product in 3 variants with different size of grain: 0.6 – 1.2 mm / 1-3 mm / 3-5 mm.
