I need help with setting up aeration for my 1/2 acre pond. The main purpose is to keep the pond from completely freezing over during the winter so my ducks will have open water. I am also hoping it will help with the fish life and algae/weed issues that I have.

The pond is setup so that it steps down 2-3 feet every 2-3 feet towards to middle. It's roughly 20 feet at the deepest point from what I was told by the original homeowner.

I was hoping to have two separate diffuser setups to have multiple points for aeration.

I've tried my best to read through similar posts in the forum, but need help with where to start as far as purchasing and piecing together all of the components.
