lol okay, i think youre getting yourself too worked up over it! the fun level is probably dropping to "will my insurance cover it all? what will be damaged?" where it needs to be, "lets see if i can get a tank the size of my wall next year!"

although its good to have a plan set up.. but just check your seams, look for bowing etc..and make sure its on a LEVEL surface, im talkin the bubble completely in the middle of the lines! that alone can potentially be a disaster sooner than you think;especially acrylic tanks, they must be completely flat on the bottom or most likely would crack. glass on the other hand is only necessary to have the "boarder" of the glass, the trim, flat and even,and normally in these situations, delt with by putting styrofoam underneath.
but just enjoy it!! i mean..id worry more about weight if that was the situation rather than wear and tear..i have my 125 with a 300Lb stand, over a basment, which recently collapsed from a coalmine..and the house is 70 years old!, its jacked up of course...but..id worry about my weight issue over time rather than a low possablity of a leak
