Issues with large tanks involving moisture

[beaglelax]

As it state i have been building my tank room and im a little concerned with moisture with the tank and evaporation. Is it better to get a Fan that will suck the air in the room out direct it outside the house. Would a good De-humidifier Work better to draw the moisture. The room is done with the same sheet rock as with bathrooms to withstand moisture but its got to go somewhere.

Any info on the best way to deal would be greatly accepted and if there is a good quaility fan unit that reefers are using in Your or their rooms please let me know.

thank you
