Thanks guys. I did the bucket test last year, well actually it was the jar test but i used the amount of alum it called for. I can double the amount if you think it will be better. I've been at the ranch hunting with the grandson or I would've responded sooner. I have been seeing more plant life areound the edges of the pond so I assume it's growing a little farther out also.

It's true hard work never killed anybody, but I figure, why take the chance?
