So I recently received a free 220 marineland aquarium from a friend. He said it was perfect all the way until he broke it down. I brought it home and started piecing everything together. After building the stand and about to get ready to set everything up. Well started leak testing it 2 days ago and found out there is a leak in the bottom. I've read everything I could I possibly read about resealing a tank this large. It's a free tank so I don't mind taking time and doing everything I can to make it work. Now I know I shouldn't reseal a tank this size with it being my first time but I'm down to give it a try. It's a lot of water to be playing around with but I would leak test for as long as I need to. I'm thinking I could build a frame out of 2x4s and plywood to hold the glass in place and help hold up the glass so the weight isn't too much on the silicone. Is this possible with time and little elbow grease or should I just stay away period? I plan on using rtv 108 silicone.
