Bender,
I have recently dug a pond and will fill it exclusively with well water. You mentioned in a thread the use of a venturi that would assist in the issue of well water having no oxygen. When I clicked on the link, it was not valid. Can you please send to me the info that was in the link?
Here is the link to the Venturi pump I am using:
http://www.aquaticeco.com/subcategories/3537/Venturi-Low-Cost/Venturi/0I am using this fitting to oxygenate my well water because I am adding the well water directly to the bottom of my pond to keep it cool for trout. If you do not have temperature concerns, I would dig a shallow trench from the windmill to the pond and line it with stone then run a line from the well to the windmill and dump it into the same trench. The water crashing into the rocks on the way down to the pond, especially with a 12' drop, will do a better job than the venturi.
I think Bruce Condello was successful in raising DO levels in his pond using well water and sweeper nozzles positioned horizontally to the pond. You might want to search the forum for sweeper nozzles and see what comes up.
