From what Ive heard a HRV is the best option for tank room.I believe it stands for Heat Recovery and Ventilation,I believe they exchange humid air for fresh outside air,hopefully someone else can chime in a bring you up to date on these cause thats all I know about them but they are suppose to be really good for aquariums and such.
