Does anyone know if there are any pond pumps that also refrigerate the water
that passes through it? It's getting really hot here in the Sacramento Valley.
The pond got to 80 today and could get hotter. Throwing the contents of the ice
maker into the pond only lowers the temperature by one degree. Not really much
help.

Do you have waterfalls, sprayers, spitters and floating plants?

Might want to get familiar with Doc Johnson's article on "Hydrogen
Peroxide For Dissolved Oxygen."

He also has several articles about oxygen in the water, just do a
search for oxygen on his site.
