I have a 1/4 acre pond averaging about 8-10 feet deep in Northeast, TN. In 2020, we had the existing 1/8 acre pond mucked out to the average 8' depth, then enlarged it to double the size to about .25 acres.
Each year, we've had a major problem with duckweed covering the entire surface.
Currently (Jan '22) the pond water is opaque with clay sediment from the excavation but is steadily clearing.
The pond is spring fed, with one of the springs about 400' away run through a 2" pipe with a sediment trap. Flow from the main spring is about 14 gallons/minute. If my math is correct, the pond turns over every 145 days or so.

Questions:
Would aeration be beneficial considering the turnover rate?
How many diffusers should I use and at what depth?

Thanks.
Edit: Would it be beneficial in any way to wait until the pond clears on its own before installing the aerators. Based on the experience when we had it mucked out, that will take about another months.
