So noticed last night the front of my frag tank has a slight bow in it and the center of the top brace in the back came unglued. I have no reason to believe the owner is slipping one by me and that it likely came unglued during the move. I need to re glue the back of the brace but am not sure how to do it. Do I need to drain the entire tank down and clean and prep everything? Can I just drain main display down wipe everything down and glue in place as a repair? Do I need to remove and reflux to whole brace or can I just lift the area that is unglued and glue that specific area? Any help and guidance is greatly appreciated!
