In an aquarium, the substrate is the foundation for an appealing design. Our substrate Aqualit is not only suitable for decoration but also practical in use. The biological substrate made from clay and loam contains supplementary minerals that stimulate plant growth and provide a good hold for the roots. Thanks to its lime-free composition and essential trace elements, our substrate Aqualit promotes healthy root development and robust plant growth, ensuring that your aquarium inhabitants feel particularly comfortable and that the biological system in the aquarium remains balanced.
