Thanks Mike, and I certainly appreciate your thoughts QA, as well. You both bring up some great points. As this is just my second year dealing with pond stuff in general, and my first with aeration, I obviously have lots left to learn. I too, am excited about the temperature drop, but just don't know yet how much to attribute to the recent rain and how much to the switch to nighttime only aeration. Time will tell. I wish I could have some sort of surface agitation going but, again, no power close to the pond. I'll continue to monitor and will keep you posted. Thanks again everyone for all of the great advice and ideas.
