[compost_tea] Pumping air in is not the best way to aerate your tea

Very little oxygen is actually dissolved from the air bubbles. Most
exchange takes place at the top where the air/water interface is.
This is done from movement of the water at the top and that's where
most of the dissolved oxygen is.

When a fish in a poorly aerated tank is gasping for air, why do you
think it goes to the top.
