Pond Boss Forums AERATION Should I aerate? aeration only during the day

Yes, you can run the tubing from the barn. Depending on the CFM reqirements of the diffusers, the 500' run of tubing might be sized differently.

Unless you can positively guarantee that each diffuser will be set at the same depth, you will need a manifold at the pond to regulate air going to each diffuser.

I have a client that is running air to a pond where the diffuser is about 600' from the compressor. Single rubber membrane diffuser, 3/8" ID airline the whole way. The pump runs 4-5 psi line pressure. But, that's not something that I recommend, I doubt that there is enough turns in the pond to properly aerate it.
