Yeah, I've moved my 150 by myself unfortunately... I definitely do NOT suggest doing that! 2 guys can easily move that. My wife and I moved my 150 to the closet last month with no problem, and she's not that strong.
Vinegar and lots of razor blades will get the tank clean. I remember my 150 when I got it had coraline algae all over it. About 10 razor blades and a gallon of vinegar later, it looked brand new.
"What, exactly, is the internet? Basically it is a global network exchanging digitized data in such a way that any computer, anywhere, that is equipped with a device called a 'modem', can make a noise like a duck choking on a kazoo." - Dave Barry
