Not only will fish tank substrate give your aquarium a whole new look, but it provides a natural base for aquatic plants to grow – which can make it an even more enjoyable place for your fish to live and thrive. Live plants need aquarium soil to enhance root growth and provide mineral-rich nutrients. Planted tank substrates are made from mineral-rich volcanic rock or easy-to-clean clay gravel that's also used as aquatic soil for outdoor ponds. If you're looking for a more luxurious look, you'll find shimmering stones, translucent glass beads and metallic gravel to use as a bottom layer of your fish tank. All of our aquarium substrates are non-toxic and safe for freshwater tanks. Of course, you also want it to make your home more beautiful – which is why we offer products in so many styles, including glow-in-the-dark, brightly colored, metallic and natural colors. Browse our latest range to find the right aquatic substrate for their home – and yours.
