EC drop due to water aearation?

Im struggling with temps as I know a lot of people are this summer, and with chillers costing more then my nights worth of fun, I thought id try moving the air pump outside the tent... Simple, and I know is been done before and its widely known and used, I wanted to say I lost fuck all. It did jack shit. don't bother.

On the other hand I did notice my ec reading dropped .2! Only variable is I changed airpump to a gh unit that could pump up a tire I bet. weird. now im "underfeeding"?

Frozen water bottles are the most efficient way. A small chest freezer can be found for cheap and uses little energy.
