I saw a few people asking about the needed PSI at different depths:

To place air diffusers at the deepest areas of your pond you must ensure that the pond aeration equipment that you purchase can deliver the air down to those depths. This is dependent on the PSI levels that the pond aeration equipment can compress the oxygen into the air lines.

For every 2 ft of depth you will require 1 PSI of pressure � so make sure to ask your vendor what is the maximum PSI that their pond aeration equipment�s maximum PSI level. For example, an aeration system that can produce 6-8 PSI will work with ponds that have depths of 10-12 FT. The higher the PSI levels the deeper the air diffusers can go and the more air that will be produced at those levels.
