Canyoncreek, Have you noticed any improvement with the pellets you are using? I sent you a PM.
I am trying to revive an old pond. It is about 20 years old and was covered In brush around the edges. I had it partially re dug. It is 3/4 of an acre. It's a u shape with a large point down the center. I currently am using 4 double headed aerators on a 3/4 horse pump. I use a product called pondvive. I'm looking to get rid of the pond muck. It's pretty thick.
