A post by mglanham showing some results.
Here is an update on my pond progress. On Sunday, I mixed 700lbs of Alum in trash cans with a trolling motor. I threw half of it from shore and the other half from a boat. I also did the hydrated lime. I only treated one half of the pond, but there was a good wind which I believe carried the Alum to the other side of the pond. When I was finished I noticed absolutely no difference.......I left thinking I hadn't applied enough.
I returned three days later to check on things and the second picture shows you what I saw.
