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.


Here is an idea that comes from a friend who drinks a lot of beer. Take a
strong cooler (tuperware or better), and coil rubber tubing into it, then pack
the cooler tightly with crushed ice. Connect the pump to the tubing and run the
tubing into the pond. The ice will stay frozen longer, and it should help cool
down the pond (depending on how big the pond is). You can upscale this idea as
needed. It works great for beer. Try it and see if it will work for the pond.
You should also reduce the flow rate somewhat to allow the water more time to
cool down in the tubing. Copper tubing works better as a heat exchanger, but
then you have to buy a pipe bender and do all the bending at all the right
places in order to coil the pipe into the cooler. If it works, you might
consider permanently installing intake and outtake connectors for the
pipe/tubing through the cooler so that the cooler can remain sealed. Sorry,
it's the best that I can do for now. Good luck, and keep us posted on your
eventual solution. You should also try to provide as much shading for the pond
as possible (just don't cover it with black plastic).
