Pond Boss Forums AERATION Systems questions Manifold Location

Hello,
I'm planning the aeration system for my new pond, and I have a question about the location of the manifold. I will have my compressor located at my barn, which is 170 ft from the edge of my pond. The first diffusers will be located 100 feet from the edge of the pond, and the second diffusers will be located 200 feet from the edge of the pond. My plan is to run a single 5/8" buried line from the pump to a manifold at the edge of the pond. I'll split into 2 different 3/8" self weighted lines from there. My question: Is this setup ok, specifically locating the manifold 170 ft from the pump? Thanks much -- long time lurker...

Here's a few pics of my pond under construction:
