Why I say I would aerate half is because the existing pond before I made it bigger was a little over 1/2 maybe .6. The way we made the pond bigger was to dig out the new part and then from the outside remove the existing dam or berms. It created a island with a about a 25 foot opening at each end going into the new part. The newer part is more like 8 feet with steeper sides. The old part is where I figure the aerator would be best. I went threw this year with no aerator and I think it went ok but I am sure a aerator will help make things even better.
Trailsguy.. it sound like you have something that might not cost to much to do. Is it something you put together or bought as a kit.
The solar thing was just me wanting to try solar with something.
