Wow! I'm sure glad this thread got resurrected....
Ken that's exactly what I thought. To good a thread to die. I had bookmarked it, and referred to it repeatedly before I considered Alum. Rex and all the other posters did good.
Although I chose not to Alum the primary pond I had originally considered, I have another one that could really benefit from it down the road. It's a cow tank also, just a lot bigger. It stays muddy, and if the Alum does to it what it did to this tank, then that's a home run.
