ScottS,You're right about the humidity minimizing it's effectiveness. I imagine you could still get satisfactory results if your volume is high enough. In other words, if you could divert ALL of your return water into an evaporator and get it high enough so it has some "air time", I think you would see a difference. Run time is important, too. I have to run 8-10 hours daily for the effect I want......of course, I'm running the pump anyway so it's no big deal.I have a fountain that I've messed with in attempts to lower the temp of the water but I have found it doesn't make a noticeable difference.
