35 acres is a lot of water to try and aerate on a normal budget. IMO we should look at a cost benefit analysis.
What are your main goals for the pond?
What comprises the fishery species?
What is the fish harvest per year?
Do you feed the fish?

Since you have water shield and water lilies they can help sequester nutrients and promote "clearish" water. I would not kill all of them and best IMO to maintain about 30-50 shoreline coverage. What is the water clarity? To best determine that with a relatively accurate number create or build a Secchi disk. Simplest is use a white Kool-Whip lid attach it to a cord so it hangs horizontal or even more simple tie a cord to a all white coffee cup. Lower the device into the water until it disappears take the measurement of that depth. Report back here with answers.
