If you take a jar of the water and let it sit for a few days does it settle out?
Yeah, I mentioned it in an earlier post, but I did that with a 5 gallon bucket and in a couple days, it was good and clear. There was a grey clayish material on the bottom of the bucket.
I was going to go the alum route, but I saw a couple posts on here that mentioned if the clay settles out, then you have something in the pond causing it. Wind or fish???
