While it seems that there could be some aeration to the reservoir, the amount of water
the fogger would actually use in that 10 minutes probably wouldn't be that much. You'd more
than likely end up just adding excess temps to your res.
I understand the purpose of experimentation, and by all means don't let me stop you.
I would just imagine an air pump would be much more effective for what you're trying to do, and
maybe even use less power.
