Fish Tank Gravel, Sand and Stones

Whether you love muted natural hues, vibrant shades or something in between, our fish tank gravel, sand and stones makes it easy to design an aquarium that suits their space – and yours. Colored gravel is the classic landscape foundation for freshwater tanks. High-quality aquarium gravel assists in mechanical and biological filtration for the entire tank. Plus, it comes in a wide variety of colors, from neutral white, black and natural tones to ultra bright and glow in the dark. Keep saltwater tanks healthy with live sand, which contains beneficial bacteria and sea minerals like calcium. Freshwater aquarium sand can be pH neutral, while specialty blends are made for fish like African Cichlids that prefer hard water with a higher mineral content. Aquarium stones add accent and interest. Use one large rock or several stones arranged in groups. All of our aquarium rocks, pebbles, gravel and sand are non-toxic and safe for aquarium life. Be sure to read the packaging of each product, as some natural materials contain high levels of minerals that can alter the pH of the water and are suitable only for reef or saltwater tanks. From authentic seashells, black stones, river rocks and white aquatic sand, to colorful gravel and brightly colored, translucent artificial stones, our collection can help you create a fish tank that complements their natural beauty – and your home.
