Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? So, what should I do?

Welcome to the forum!

With that muck level, to me, it's not that big of a concern. If the pond gets wind enough to ruffle the water, an aeration system wouldn't really help that much, except in winter if it were to freeze over for any long length of time (because of the depth of the pond). Since you have Coppernose in there, I doubt that is the case. If there are a lot of trees around, or it's in a hollow between hills, aeration might help, but I think there might be other things that can be done with that kind of $$ outlay. Solar isn't cheap.

Manage the organics that fall/blow into the pond. Leaves, grass clippings, etc. Minimize those. The more that the mucky areas are stirred up (as in a swimming area) the faster that the muck will decompose. You can add bacteria, but it is a slow process in reducing the muck, maybe a few inches per year, and for best results you have to add bacteria on a continual basis, it's not a one time shot.

Any CNBG that you add should be a minimum of 7"-8" in length to avoid being eaten by the bass. Next time you are fishing and catching bass, weigh them too. There is a relative weight chart in the archives, and if the bass are under that weight for length, then it's time to start removing about 40 pounds of bass this year. (of all sizes, but especially the skinnier ones)

I would concentrate on catching crappies too, and removing them.
