I have an older pond and am working on a pad near the pond for a barn we will have built soon (with electric). My pond is a bit over an acre and about 12 feet deep maximum. I have had 2 partial winter kills in the last 15 years and want to add the minimum aeration that will likely make another winter kill unlikely. Would a single diffuser likely work? What type would be best, and would putting it under the floating dock also help with possible ice damage to the dock (none yet after 15 years though). What minimum size compressor might work? I am looking for durability, low operating cost, and low noise. My plan would be to invest in quality to reduce later costs. Any help or reference to web info is appreciated. This will likely be a 2017 project after the barn and electric are installed. Since I have only had winter kills, My plan would be to run this system only when ice cover is on.
