Aeration as mentioned keeps oxygenated water on the bottom providing it is sized properly for pond size, shape, and depth. Bottom aeration slows the aging process of the pond assuming all things or influences are equal in a non-aerated and aerated pond. The aerated pond will stay overall "better" water quality wise than the non-aerated pond. A 2 acre pond will often require 3 to 5 bottom diffusers depending on pond shape & depth. Generally only water bottom areas deeper than 5-6ft need to be aerated. The shallower areas (<6ft) will usually be mixed pretty thoroughly by the wind assuming the pond surface is windswept. Deeper ponds in TX (8-12ft) are generally a good idea if drought periods occur in your area.
