Oh ok that makes more sense now! Still though it is not worth doing for just a few times at 20 minutes a day and compressors suck a lot of juice. The situation you are talking about would be someting one might do for an emergency when you needed some DO and you needed it like right now!! And even then don't know how much good it would do???
What you could do is this.
Get a good air pump keep it up near the house and run you a pvc pipe or some kind of plastic long type hose all the way to your pond. Once your at the pond attach weighted line from Ted at Forever Green he has good prices on his stuff! Then attach two diffusers to weighted hose somewhere in the middle of your pond. Run air about 8 to 10 or 12 hours a day on a timer. Now your doing something worth while for your pond and your fish will love it!
