Aquarium Sand

About

Build a cleaner, more natural reef foundation with aquarium sand selected for saltwater aquariums and reef tanks. This collection focuses on CaribSea live aragonite sand options like Fiji Pink and Arag-Alive Reef-Grade, giving you reef-safe grain sizes that look natural, support beneficial bacteria, and work well for common sand-sifting fish and invertebrates. Choose finer reef sand for burrowing livestock and a softer look, or a slightly larger reef-grade grain when your tank has stronger flow. Whether you are starting a new aquarium, refreshing a sand bed, or dialing in your aquascape, these saltwater aquarium sand options are built for stable, beautiful reef systems.
