Pond Boss Forums AERATION Should I aerate? to aerate or leave well enough alone!

Aerate.

Heavily stocked, feeding, surrounded by leaf-dropping trees - all indicators flagging potential fishkills. Proper aeration will help avoid that.

If you don't have a separate reason to have electric located at the pond, you can put the compressor where you already have electric and run the air 400 feet easy, cheaper than running electric.

You won't get it in before the water cools off too much for any worry that aeration would help other than possible Winterkill - I would get it all figured out and have it installed by next Spring.
