A few years ago I bought an oceanic 110 on Craigslist and it leaked when I bought it but I was willing to reseal it. So I did. It held water for more than a year then one day at 2:30 in the morning I noticed it had started to leak. I thought water was just splashing on the covers and running down the side or something. But then I found that there was about 3/4 of an inch gap between the front panel and the center brace. So then I tore it down and resealed it with an additional piece of glass siliconed between the front and back. It held for a few months no problem then one morning at 4:30 the new brace was ripped off the back and laying along the front of the tank and the back of the original center brace was unattached from the rest of the tank. So again I had to tear it down and move the fish. I went way overboard with the silicone the second time so idk what to do. Either sell it as a terrarium or fix it for a 3rd time.
