The Penn-Plax Bubble Wall is designed to create a dramatic mist of healthful bubbles in any aquarium.
It comes complete with suckers to attach it to your aquarium and a free converter to add extra bubbles walls.
Made of polycyl, this tough material resists clogging and will also stand under repeated reconditioning.
In hard water areas, mineral deposits may clog any air stone. The Bubble Wall is the only aeration product which can be easily regenerated. To do this simply use a pin to pierce holes into the Bubble Wall.
