Hey thanks for the replys. I would say my pond is 250-300 yards away from my house. I wondered if I could trench in an air line but I thought it would be too far.
I have a 1/3 HP blower I have left over from the late 90s when I owned a bait shop and I remember it came with calculations on what size pipe and how deep you could run your air stones. I remember it restricted the CFM quite a lot running smaller pipe. I had it rigged up with 2" Pvc then of to 3/8" hose. I know this is a whole different pump and i cant find the instructions.
I will do some checking but from what you guys say looks like trenching an airline would be the way to go.
I had talked to the Elec. company about running electric on the other side of the pond about 3/8 mile from the road when I was planning on building a house back there and there estimate was like $3000.
