Goose Pond gets an solar aerator...

A temporary setup since ground is hard for hand digging. I will mount the 2 panels on a nearby building.

Powerful aerator for my pond. It is still in the works with no liner, so it doesnt hold water well in the summer.

After digging an existing pond deeper last year, I purchased a RPS aerator to deal with goose muck. In the middle pic, you can see the brown box with tiny solar panel on top. It houses the pump and the controller and a fan to cool the pump on hot days. I primed it brown to be less noticeable.
I placed the system near the electric top line fence so I could use the same grounding rod. The kit comes with solar panels and everything I needed. The entire kit is about 2-3000$ but I got this one on sale for much less. After a bit of research, I found most cheap aerators break shortly after using. This one has a 2 yr guarantee and RPS has excellent support.
As with the my previously installed RPS solar well pump kit, it was an excellent product. It comes with easy instructions, several versions of wattage power, 200w-800w and all the parts you need. In about 30 minutes I had attached all the parts and tested it in the murky pond. I still have to finish ditches for installing solar panels on shed and trenches for burying the aereator hose in the ground (otherwise geese will nibble on everything).
At some point, I will still need to figure out how to retain more water in warm weather without a goose puncturing a pond liner. So far when I dug deeper there was a grey clay that looked just like bentinite in this lower section (see pic for how this part has not dried up yet). When full in winter it is about 10 ft deep. But now in a warm May its about 5 ft.
When I turned on the aerator to test it, I found it was very powerful. I think it will help process the muck generated by all the goose poop. My two geese spend a lot of time in the pond year round. Mating is easier for them in a body of water. And in summer they seem to get very hot. Imagine all the goose down they have hiding under those feathers. It's why they can hang out in winter in the snow for hours.
