Marina Decorative Aquarium Gravel – Surf Mix (1 lb) – A 1 lb assortment of aquarium gravel in “surf” colors (a blend of ocean blues, aqua greens, and sandy neutrals). This gravel mix is perfect for creating a beachy or tropical theme at the bottom of your tank. Each piece is coated to be completely fish-safe and will not leach or fade. Spreading this gravel in your aquarium can enhance its visual appeal – the cool-toned pebbles reflect light beautifully and make the underwater environment more inviting. It also serves as a stable bed for planting artificial or live plants and provides surface area for beneficial bacteria in your aquarium.
