I have read that the barley will not work in this case. From what I understand the theory behind the alfalfa is that it is rich in nutrients and as it decomposes will clump the suspended clay together to fall to the bottom.
If it is a waste of time, I'm not too worried about it, I will end up getting the alfalfa for next to nothing if not free anyway. May try it in a 5 gallon bucket first. I have talked to Rainman on the subject as well.
I am not sure on exact age of the pond, I do know it is over 20 years old. We just bought the place in February and don�t know if it was ever clear. I do know that one of the old owners, several years ago, raised CC in it and drained it every year.
Here are a couple pictures of it. The water has dropped about 2-3� since these pictures. Thanks
