Thank you for all the insight and helpful advice. The pond is about an acre and a half. The deepest part of the pond is 14 feet deep. The electrician that looked at it for me said that it wasn't feasible to run a line from my breaker box because of the voltage drop. He said I would need to run a second primary service to the pond. I stopped pursuing it at that point. The pond is about 40 to 50 feet below the elevation of the buildings. It might make the run a little longer than 1000 feet but I should be able to slope downhill all the way to the pond. The quote I have for the electric aeration system is for a 3/4 HP Sentinel Aeration System with three double disk diffusers. It includes 3/8 inch weighted tubing. For the single pipe to have a greater area than the three pipes combined it looks like I should use a 1 1/2 inch pipe from the pump to the manifold. What type of pipe should I use? Does someone have a name of a manufacturer or link to the type of pipe that should be used?
