Figured I'd post this here, cause I've seen one or two posts about it in the past, but it still worries me, and figure more will have the same question. So I emptied one of my 75gal glass tanks the other day to make room for a larger tank, and moved it out to the garage. A few days later we had a huge cold freeze, and I must have had some moisture up under a portion of the top frame cause I went out in the garage last night, and just happened to notice several cracks in the frame in one spot. What are some peoples thoughts on stability, and does this need to be fixed, or should it be fixed? etc,etc... any and all thoughts and ideas are welcome (I think 
)
