The water quality "looks" good, but I don't have a way to test it. It's fairly clear with a little bit of a green bloom. No odors.

The fish clean up all the feed in about three or four minutes, sometimes faster at the evening feeding.
I still have nine feet of water over the deepest quarter of the pond, and eight feet over the other deep quarter. Lost a lot of surface area in the shallows.
No aeration. The pond has been filled for less than a year.
