| The Penn Plax Deluxe Bubble Disk creates the aeration and surface
agitation needed for a healthy pond or aquarium.
Great to use in aquarium decorations to create a "volcano" of
bubbles. Breaking bubbles at the surface temporarily clears accumulated
organic "slime", allowing oxygen into the water and carbon dioxide out.
Round design provides an interesting effect.
For use in freshwater or marine aquariums and ponds. Uses
standard airline tubing.
