Recirculating pumps
As well as looking nice, fountains can be used to make the surface of water in a pond rough so that mosquitos do not lay their eggs in it.
For a fountain you need the highest lift (say 6 feet), for the least power usage (say 25W), for the least money (say $27) so you can afford a few of them.
Details here .
Ideally it is best to use a 12V DC pump so that you have the option of efficiently running it from solar without having to convert 12V DC from the solar panel to 115V AC.
If you don't initially have a solar panel then you can run the 12VDC pump using a power brick from 115VAC.
The nice thing about solar is that your enjoyment of the fountain is not degraded by thinking about your electricity bill. Solar also means you potentially don't need an on/off switch because the fountain will just run whenever it has power to do so , which of course will be more on sunny days (which is when you want it the most as you will be more in the yard). A negative with solar is that there will be gaps in it running during which mosquitos will be able to lay their eggs.
Here's a cheap solar powered fountain but try to find a longer lasting more powerful one...
