Aluminum sulfate will clear muddy water. I used 300 lbs. 4 or 5 months ago in my acre pond. It cleared about 18". I thought I wanted it clearer but now after learning a number of new things this depth is ok with me for now. I had a number of email conversations with K. Duffie before proceeding. He put me onto an article at
http://www.sdafs.org/ concerning clay turbidity in pond water. You should go there and get the article. I have 300 lbs more in my garage that I will apply in fall. Read the article and talk to Kelly before proceeding with this method.
