Penn-Plax Deluxe Bubble-Disk Air Stone Green/Blue, 4 in, Medium

Give your aquarium a lively lift with the Penn-Plax Deluxe Bubble-Disk Air Stone in green and blue, medium 4-inch size. This disk rests on the bottom of your tank and sends up a steady stream of bubbles that adds oxygen, movement, and a calming visual rhythm.

• Bubble disk format creates that soothing rising-bubble effect that draws the eye to your tank.
• Green and blue coloring tucks neatly into your aquascape among gravel and plants.

• Sized to suit mid-range tanks where a small disk feels sparse and a large one feels like too much.
• Simple to reposition on the tank floor as you fine-tune your layout.
• Penn-Plax Deluxe construction is built to keep delivering bubbles in your everyday setup.

A steady ribbon of bubbles does more than look good, it helps keep your aquarium oxygenated and active for the fish you love. Hook it up to your air pump, set it where you want the show, and let it run. For owners who want dependable aeration with a built-in touch of ambiance in a size that fits most tanks, the Penn-Plax Deluxe Bubble-Disk Air Stone in green and blue, 4-inch medium, is an easy, satisfying addition to your aquarium.
