Trying to figure out whether to treat with chemicals or bacteria. We have a pond that is about an acre in size that is in the bottom of a hollow in the middle of some timbered land (weekend retreat). The lay of the land makes certain that each fall leaves find their way into the pond. I assume this is what is feeding the fil algae. At present, most of the algae is on the bottom (completely covered), although there are two mats on the surface already.

I have read most all of the other threads on fil algae, but I guess I haven't come to a conclusion on what to use. A game plan if you will. Chem's? Bacteria? The corn meal (bacteria solution)? Combonation? Would aeration be beneficial?

If anyone needs more specifics let me know. Photo below for reference (taken Jan 1, 05).
