Understanding the concepts of aeration.

There are many misconceived ideas about aeration.

Two common fallacies are:

1. Large live wells are required to sustain a large quantity of fish.

2. Large live well pumps are needed to move large quantities of water through the live well to keep live bait and fish alive.

To understand what is really needed in proper aeration, it is best to take a look at ourselves.


  • If we were enclosed in a large airtight room we would be able to breathe for many hours before we would consume all the oxygen.
  • If we were in an airtight closet, the oxygen would be consumed a lot quicker.
  • If we were swimming underwater without a snorkel, the oxygen in our lungs would be gone very quickly.
  • In all cases, without additional oxygen we would expire!

However, we could stay alive indefinitely, if we could use a breathing tube or snorkel that was in contact with outside fresh air or oxygen. It would not matter about the size of the container that enclosed us.

An aerator is to a fish, what a snorkel is to us! The smaller the air bubble, the more slowly it will rise, giving it more time to dissolve in the water.
Due to the higher density of salt water, air bubbles are usually smaller in salt water than in fresh water.
A large 20mm bubble has a volume of 4.19 cm3, and a surface area of 12.6 cmsq
You could make 260 small 3mm bubbles from the large bubble. They would have a total surface area of 83.6 cm2. This is 6.6 times the surface of the 20mm bubble.
The small bubbles, can theoretically aerate 6.6 times as much water with the same amount of air.
Knowing the importance of air bubble size, the effectiveness of different aerator systems becomes readily apparent!
