Oops, I meant I was hoping to convince BILL to tell me about the cheap diffusers.

I went to Home Depot and they had the 1/2" poly tubing that Bill mentioned. Only $8 for 100ft. You have to get it from the plumbing dept though.

Now for some more questions...

If I am running a 150' line off the compressor does that cause me to lose significant CFM? I tried it in my sink using both a 2' piece and through the 100' piece and didn't notice much of a difference.

We tested the pump in the basement and the wife informed me it sounded like someone was using a jackhammer down there. I now am left with putting it by the house, but outside, or by the pond. What are the major problems with running an extension cord out to a spot closer to the pond? People have cords out during the winter running their Christmas lights...

Also will running an extension cord increase my electric bill, or would it be the same?

Thanks again for all the help...oh yeah, Bill asked what I wanted the aerator for, well it is both to keep a hole in the ice so I don't have to provide water for my ducks and to aerate the pond as I have way too many ducks for the size of my pond, but like them anyways.
