Get three estimates from good aerator people one of them Vertex. Watch for cfm (air volume) of the compressor. The more air the larger the diffuser and quicker it can turnover the pond. If the pond stays reasonably clear you would not have to run the aerator 24/7. A good aerator should easily mix one pond turnover in 1-2 hrs. Then run it twice a day turning it over twice a day.
An aerator will not eliminate the green string algae as you will learn. Cut back on feeding the minnows. maybe 1/4 cup a day or just 3 days a week.
Now saying 48x48 is 2300 sqft if pond is square 0.05ac ave depth 4ft = 65000 gallons ; And a round pond at dia 48ft is 1800 sqft. = 0.04ac = 53000 gallons.
