• Natural & Safe for All Aquariums: With a grain size of 3-5mm, this substrate is 100% natural, free from artificial colouring, and completely safe for all aquatic life. It does not alter water parameters such as Gh, Kh, or pH, ensuring a stable environment.
• Perfect for Plant Aquariums: Ideal for every biotope, this gravel is especially suited for planted tanks. The 3-5mm grain size promotes strong rooting for aquatic plants, fostering healthy growth while remaining safe for all organisms.
• Enhances Natural Beauty: Every aquarium enthusiast knows that substrates do more than decorate—they shape the tank’s environment. This natural, uncoloured gravel provides an authentic, organic look that complements your aquascape.
• Boosts Fish & Shrimp Colouration: The natural hue of this gravel enhances the vibrancy of fish and shrimp, making their colours pop and creating a stunning visual effect in your aquarium.
• Easy Preparation: Before use, lightly rinse the substrate. Avoid over-washing, as this can be time-consuming. After adding to the tank and filling it with water, slight cloudiness may occur, which clears quickly once filtration begins.
