Thank you both for the time, I will be ordering this stuff tonight. what depth is a good depth to put my difusers? my pond is 15 feet at the deepest and has steeps banks on 2 of the sides with the 3rd side gradualy sloaping to 15 feet deep. 70% of the pond is 12 to 15 feet deep. The pond looks like a basbeball diamond. the gradual sloped area is where i have 80% of my structure.

A weeks worth of vacation, 59 hours in a John Deere 160, 2 logs of Skoal, 1500$ in fuel, Lots of help from the neigbors and my old man, and a wife with an open mind to let me dig a pond at are cabin. All i can say is life is good!
