What is the difference in flooming as a method of areation?” –>
First let us describe flooming. Flooming is accomplished by a pump ejecting water upwards to the surface of your pond from the bottom. The result is the rippling of the surface. Similar action to that of an air stone on the bottom but without air bubbles. No air bubbles allows you to see the fish easier. Flooming also decreases the probability of failing to replace the air stone. Areation of water takes place on the surface of the water and its contact with the air.
