Well as i have a window right behind my tank i will have one blowing in at each end and duct to the window with one blowing out. That way the heat goes right outside with any water in the air. That is IF the wife stays out from behind the tank long enough for me to do it without her knowing
then i can say "look babe now the heat goes right outside!!!" much better than "hey love you mind if i drop another wack of $$$ on the tank so i can removed heat?"
