Hey Greg,

Thanks for the reply. I lived outside Marietta in Acworth from '93-'99. We now live, and the ponds are located, 1 hour North of San Francisco in Sonoma County, California.

I have been in contact with Vertex/Aqua Systems and am waiting to hear their recommendation for the lakes. I'm thinking each needs at least a Air 4 XL. I am curious to see if we need to fertilize with aeration to the the optimal Secchi disk readings. It is encouraging, at least, to see a plan coming together.
