Produced great air bubbles needed by your fish.

Great for keeping your minnows alive while fishing.
Simply said, not all wood are the same. This wooden diffuser  tested works and last longer.

Works for both Freshwater or Saltwater

You may need to attach to a tube holder or suction cup holder or attached to something heavy
  to stay in place. Otherwise, it will float.

We are not responsible if you air pump is defective. The better the air pump, the abundance of bubble it will produce.
See photos and videos.

Note:
When use in freshwater, bubbles are bigger.
When use in saltwater, bubbles are smaller and finer.

The video may have different size, but this posting is for 1" cube size.
