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.
