Pond Boss Forums AERATION Systems questions Guidance for my pond? (0.6 acres, southeast MI)

Purchase a cheap wired indoor/outdoor thermometer. Go out in the pond in the deepest water, take temperature measurements every foot. If the temperature doesn't vary more than a degree or two, you don't need to add more aeration.

If you still want or need to put aeration in the pond, I would bury 1" poly tubing from the barn to the remote manifold at the edge of the pond. THEN transition to the 5/8" weighted airline.

During the winter I would shut off the one in 5' water depth and just keep the one in 4' water depth running. I would just look at rotary vane and rocking piston pumps. The rotary vane will be the easiest to do a rebuild on, and I am pretty sure you will get more air out of one vs. a rocking piston for the same electrical consumption.
