I have a 1/3 acre pond that's 10' deep I'm trying to setup an aerator for. Its about 500' away from electricity. I was going to try to run power out to my pond, but found on this forum I could just run the air line. I just ordered a Vevor kit that has a 1/2 hp pump, 100' weighted airline, and 10" membrane diffuser. Maybe that was a mistake, I don't know.

My question is what air line would be best to cover the 400' underground? The 3/4 100psi black poly is the cheapest and in stock. Would 1" be better (would have to be ordered), or a heavier pipe? I plan on using a sub soiler behind my tractor to bury it.
