[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.
