Interesting thread especially since I can now relate to the muddy water syndrome. With the weather so dry and no rain my pond was down about as low as it ever gets so I decided to dig it bigger. The digging went great but now I have a muddy pond and fish that won't feed. I'm thinking about applying alum so this is an interesting read. But, I see every aspect of using alum discussed other than how you apply it and where to buy it. I've searched high and low and cannot find any place that sells it. Where to you folks buy it?

Gotta get back to fishin!
