Penn-Plax Bubble Wall Air Diffuser Fish Aerator, Multicolor

The Penn-Plax Bubble Wall Air Diffuser Fish Aerator creates a dramatic mist of healthy bubbles in your tank. Just connect it to your air pump (sold separately) and the super-porous, non-clogging wand will evenly distribute fine bubbles. The tough wand is made to withstand continual use. You can even connect multiple diffusers (sold separately) together using the enclosed connector to create almost any length. If the wand is too long, you can cut it with a razor blade to shorten or divide it. This is also great for use with aquatic turtles and aquatic amphibians.
