HELP!! Too much moisture in my house!!

[Kurtonius]

I need some solid advice. I have a 120 gallon reef tank and its creating havoc on my house. Black mold is found on all our windows becaue of condensation building up.

I have a baby coming in less than two months. I have to sort this out or sell my setup.

What I've tried so far:
-turn the water temp down as much as the fish can tolerate
-put a glass on top of the tank (doesn't cover the whole top of the tank mind you)

I also notice that I have to crank the thermostat on the house to keep us warm. It seems to me that getting rid of this tank is a win-win.

However I'd rather keep it if I can. HELP!!!
