Hello Malibu Water Resources:
We got the windmill up and running.
Overall it took three days.
On the first day, I put together the blades and the top eight feet
of tower.
On the second, I put together the rest of the 20' base.
On the third, I finished tightening all the bolts,
assembling the base/pump/blades,
and then with the help of three more guys,
three trucks, and a tractor, we got it in place.
I went to Joe Mescan's winmill place to see
his four examples around his pond (as seen on his web sight).
All his joints overlapped (top piece over lower piece)
so that water would stay out of the joint as we had talked about.
Joe told me that it took from four to five people
to raise a 20' wind mill on a calm day.
We used the tractor to secure the two down legs
so that they would not slide out as the top was raised.
We then used a truck with 150' of rope
attached about 4' below the compressor
to pull up the tower once it was partially up.
Three of us lifted the tower about 8' up
and the fourth backed the truck up to let it do the lifting.
Finally we used already secured lines
four feet from the compressor on the other two legs
to steady the base.
These were attached to two other trucks.
Then we were able to take our time
leveling the base and driving in the 3 ground stake rods.
I didn't get a picture of all the lines on my digital,
but will try to scan and send the regular picture to finish the
sequence.
Thanks for your help,
John Schubert

Where oxygen is really needed in a pond is at the bottom. Pond and lake bed aeration adds oxygen to all of the water, not only surface water, but to the water at the bottom as well. This is very important. Once the lake or pond is full of oxygen near the bottom, new insect larvae, snails, and other fish food can begin to live on the bottom.
By pumping compressed air out into the pond or lake bed aerator (from the electric aerator or windmill through an air line attached to an aeration stone), the rising air bubbles from the air stone bring bottom water to the surface where it is exposed to the atmosphere. Thus, large volumes of water brought up by the air bubbles lose bad gasses to the air, and pick up even more oxygen while on the surface (air contains 22% oxygen). Bacteria will breath oxygen if it is available. They like this new oxygen "banquet" in the water so well that they grow very fast, multiplying rapidly to gigantic numbers. Aeration speeds up this process of oxidizing or "burning up" the pollution in the water. Result: fresh, sparkling clear, sweet-smelling water which supports abundant fish life, free from excessive algae and weeds, and is available for live stock.
