I have a large reef tank set up given to me, and I was wondering if you all had any ideal how much this thing would weigh, or any ideal on the proper way to move it. I am trying to figure out how to move it in a few days, it is about 6 feet long, 2 feet wide, and 2-1/2 feet deep. it is a older tank glass looks like 1/2"? it is in a basement and I have to move it out a door with a few steps, just trying to figure out how many guys I will need etc. thanks
