i got a tank off a Buddy's friend its a 150 gallon oceanic glass tank for 60 dollars so i couldn't say no i brought it home a filled it up and it started to leak from the top corner and started tearing the seal down ward so i emptyed it fast and dryed it off scraped out the silicon and resealed it I'm just wondering is silicon really gana hold it together for bowing out and leaking again or do i need something to brace it
