No water evaporation?

Over the winter, cooler months def more evaporation, and notice less when it's warmer. I just haven't seen a huge difference to date. That said, I plugged the ato back in, pump ran for 5 secs then stopped. Salinity is 1.026. Guess the evaporation has finally slowed down....guess it was just timing of this happening.

I agree with Sphelps that it's probably related to the humidity in your house. When it's cold and dry my evaporation is pretty significant. In the summer months, dramatically lower.
