The Uniclife Aquarium Volcano Ornament Kit is a realistic and stylish way to add some excitement to your fish tank. Made of durable resin and polished with natural stone color, this ornament is perfect for any fish lover. The strings of bubbles from the air stone are illuminated by the appealing red LED lights, which contrast sharply with the overflowing lava and create a unique scene of volcanic eruption. The air stone produces a steady stream of micro bubbles that burst quietly to promote oxygen solubility and water circulation. The kit also includes a red volcano ornament, an air stone disc with 6 LED bulbs, a power adapter, and 4-foot airline tubing.
