Air flow of 3.4cfm should produce very good mixing in your 1/2 acre pond. With the proper diffuser, run times can easily be 4-7hrs per day in a newish 0.5 ac northern pond and produce complete mixing daily. Note those compressors may have difficulty restarting with back pressure in the airling soon after stopping. Contact me or supplier if you have difficulty. I am not familair with that special model number. Who is the supplier?
