Great input Dave, I'll dig into max runs for 220V runs. We have power available from a garage that is closer, but it will be tricky and involve a bit more work.
The thing that is nagging at me today is the ability to keep cover over the reinforced polyethylene on the sloped sides of the pond. There must be a material that can be made stable enough to avoid sliding down... then again, perhaps I'm worried for naught. I'll soon need to get this ordered.
