Thanks Bill,
Here is the comment from John Longnecker at MalibuWater.com
"Air Diffuser
-- COARSE air bubbles are good for de-icing
-- An air diffuser that releases TINY air bubbles adds more oxygen
for pond water quality. "
Your logic makes perfect sense though, the more the water moves the less ice should be able to form. The problem with testing this out is that the temperature is never stable enough to test duplicate situations. Maybe there is a study that has been done already?
I do have another question...
The pond is about 100' from the outlet. Should I run 100' extension cord, or 100' of air line? Which would be better?
