This AQUAEL product serves as a premium bottom substrate designed for freshwater aquariums, particularly those featuring natural aesthetics, lush plant life, and shrimp inhabitants. Visually, the Soil is akin to black gravel with an average granule size of 2.5 mm. Made from natural, thoughtfully selected materials, it optimizes water parameters essential for the health of various freshwater ornamental fish, plants, and crustaceans. The positive impact on the entire ecosystem becomes evident quickly: clearer water, thriving plants, and more energetic aquatic life!  How does it correct water parameters? Advanced Soil Plant is packed with natural nutrients that gradually release into the water* and positively influence key aquarium water characteristics for aquatic species: it helps lower or stabilize pH and KH (carbonate hardness) levels. As a result, plants experience enhanced growth and display a more vibrant appearance. Thanks to this Soil, fish can even be introduced on the very first day of setting up the aquarium. Moreover, this Soil enhances biological filtration within the aquarium due to its porous nature, making it an ideal environment for beneficial nitrifying bacteria to flourish. The granules also trap nitrogen compounds, thereby aiding in the preservation of a healthy ecosystem. Consequently, water quality improves, resulting in visibly crystal-clear water. The dark substrate not only functions well but also offers aesthetic benefits: its deep color makes ornamental fish, vibrant shrimps, and lush green or reddish plants stand out beautifully; colorful decorations also create striking contrasts. *The Soil continuously releases nutrients over time, ensuring long-lasting effectiveness and allowing for sustainable use without the need for frequent changes or additional nutrient supplements.
