Thanks for the input.
The pond is 3.5 acres with a max depth of 22 feet and an average depth of 8 feet (that's a guess, but it appears to be a fairly deep pond all around.) It's generally an elongated triangle with a small island at the narrow end and a small cove around the middle.
I went through one of the aeration companies that does a quote based on aerial mapping and data that I provided through their web site. I believe it was Airmax.
The system that was quoted was for everything except installation.
