Pond Boss Forums AERATION Systems questions Windmill aerator

If they haven't changed the Koenders' design since mine (2 1/2 years), the airline fitting comes out the bottom of the pivot tube (the airline fitting swivels on the airline at this point as the windmill turns), so you would have to run the airline out of the support pipe somehow.

My thought is that regular 2" (that's about what size it would be) steel water pipe would not hold up if used to support the windmill; I think it would split at the seam. But a thicker piece of steel tubing should work OK, especially if seamless (bored out solid billet).
