I explained my point very poorly.

Your relatively small, yet very deep pond will almost certainly benefit from aeration.

I could not tell from your post if you were planning to use your shop compressor for your aeration. I did not want you to burn up a good high pressure - low volume compressor.

Your pond aeration compressor will be low pressure - high volume from a much smaller HP motor. (Although at your depth you may need a little higher pressure than some of our other pond applications.)

I am NOT an aeration expert. However, if you post a question with lots of information about your situation in the Aeration forum, there are dozens of experts that may drop in to give you some good answers.
