The Uniclife Aquarium Volcano Ornament Kit is a realistic and stylish way to add some excitement to your fish tank. The set includes a red volcano ornament, an air stone disc, a power adapter, and 4-foot airline tubing. The air stone produces a steady stream of micro bubbles that help increase oxygen levels in your fish tank. The LED bulbs give off six colors of light, changing alternately to create a stunning visual effect. The resin is durable and easy to clean, while the polished finish is sleek and shiny.
