Alright well i had a bit of a setback last night. Was filling up my friends' 4 foot 150 and at about 90% filled the bottom seam failed. Water was GUSHING out and the whole tank drained. Now, the glass is fine it just needs to be resealed. Another thing with this tank is that the previous owner removed the bottom trim for some reason but it still has the top trim. My question is are we going to have to disassemble the tank and reseal or would we be able to scrape off the silicone on the inside and outside and just reseal without taking it apart?
I really need your help guys.

thats a tough one, id definately take it apart, and try to build a bottom support, maybe like build it into a stand. most glass tanks have trim there for a reason, and if it has it on top, it is there for a reason. good luck id definately do your homework
im just worried about taking it apart. I feel like id mess it up more if i did, not putting it back together level and square,etc....i was thinking about building the stand so the tank will fit very snug...how would i go about making a support for it?brich999;5106707; said:
I have a 220 Gallon 72"x30"x24" that I purchased the bottom trim was dammaged and had to be removed.... Talked to a lot of people (Aquarium Stores And Builders) and you don't need trim on the top or bottom of your tank the silicon will hold it together...BUT You Do Need Bracing At The Top Of The Tank So IT Doesn't BOW THE GLASS from the weight of the water. I don't have trim on the bottom and my braces broke off the top but I made braces out of angle Iron To support the glass from bowing. My tank has been set up from Oct. 2010 To Now without the brace on the bottom. But you need to disassemble the tank to get the silicone between the glass not just run it up the inside corners or it will not hold.... 
Without seeing the tank it's really hard to say but unless the silicone around the bottom of the tank that holds the glass panes in place is shot I would not be taking the tank apart. I would clean off all of the silicone that is primarily there to seal the tank but leave the silicone in place that holds the panes in place. Clean up all of the glass, and reseal the tank.
