My simple input as a newbie to the aeration:
I don't think you have to install it. Your temps look very similar to my area, possibly a few degrees warmer. However, you state that you want to grow the best LMB you can under ideal conditions. I think that includes aeration. With it, you should be able to increase the amount of LMB your pond holds--at least this is how I have been understanding it. Increase could be physical quantity or higher pounds of just a few fish.
You are going to invest a good amount of money in building this pond. The cost of aeration will be only a fraction of that. Now if there is no electric within say 1500' of the pond, that's tougher. Lots of sun, then maybe solar powered as one member is trying.
I did not plan on aeration myself and don't have it yet. But then learned about its benefits here, and I want to in the very near future. A new pond owner has alot to absorb and learn, most of which he doesn't know yet what he needs to know. That's where PB comes in.
P.S. What is FLHM?
