Mr. Gallus, to answer the questions my pond is about 2.5 acres. I have a � hp rotary vane pump with 3 separate diffusers on it. The narrow end of my pond is about 5� deep and it gradually goes to a depth of about 25� by the dam. There is a fair amount of this algae but it is pretty much limited to the perimeter of the pond. My pond goals are to fish and swim in it, I�m particularly interested in the bluegill fishing. As far as the amount of FA that I�m willing to tolerate, if I could get rid of it all I probably would. It is unsightly and if it gets bad the swimming probably won�t be much fun which is really bad because the swimming is the main reason that my wife likes the pond and has allowed me to throw as much money into this watery pit as I have. If it is bad for the fishing I would probably be willing to do just about anything to get rid of it. Of course what ever resources that would take would have to be utilized for the sake of making the pond suitable to swim in
. I followed your advice about doing a search for filamentous algae in the �Controlling Unwanted Plants� section and came up with 20 threads and read them all plus the 4 that Mr. Ewest posted. It seems that there are several options for getting rid of the stuff, unfortunately none as easy as I had hoped. I�ll have to think on how I�m going to try and tackle this situation. Thank you all for responding to my call for help.
