Dark Gravel - 3-6 mm
Ornamental gravel as a ground cover for your aquarium. Before use, rinse with cold water to wash most dust off. The water can become a bit turbid after the gravel has been placed, has no influence on the water quality, the water is clear again within 24 hours.
If aquarium plants are also placed in the aquarium, a nutrient medium should preferably also be used.
Place the substrate in such a way that you allow it to run diagonally to the rear, this allows you to grow depth in the aquarium and there are usually more plants in the back, which can then better root in the thicker layer of substrate.
