Bill,
Thanks for the detailed reply, a ton of information in there. I went back to the pond yesterday and to be honest most of it was gone. Not sure where it went but just a small amount of bubbles present. Haven't been back there yet today but I'll see what's there and let you know as far as a sample. The water underneath appeared to be fairly cloudy from what I could see also. I'll let you know a little later after I see.
