Loose glass brace across the middle of a 55gal

[charliec]

I haven't posted here for a few years but I remember the good ideas on this board when I got started in this hobby.  I am doing water changes today and noticed the brace across the top of my 55 gal has pulled loose from the back about a quarter inch.  It wasn't like that last week.  The tank was given to me about 8 years ago so I'm guessing it is 10 to 15 years old.  When these tanks are built, do they just stick the brace in with aquarium sealant or do they use something stronger like crazy glue?  Good ideas on how to fix this anyone?

Seems like thats a common problem in 55 from what i googled. Some say you dont need one unless it really bows. One person fixed his by manufacturing a brace that went over the rim. One person did ise super glue. Personally i dont own a tank that size but manufactiring a over rim brace sounds more of a better fix, but thats my opinion.

On most 55s the brace is essential. As it lets go the tank will bow out a good 6".
Depending on where it broke you can usually fix it. I had one someone fixed with plywood and sheetrock screws that worked like that for years. I glued one and another I fixed with plexiglass and stainless steel screws. Post a pic,lets see what you have.

A really good specialty LFS may have a 55 Gallon Frame in stock, or can order one.  The 2 major manufacturers do offer them as replacement parts.
Also, I would say that the seams of the tank would definately give way long before the glass was able to bow out 6 inches....

Nope,Ive seen it. Still fully sealed and glass bending out. Was amazed it didnt break.

After talking with my LFS I decided to clean the glass well with vinegar and rubbing alchohol and put it back in with silicone aquarium sealant.  It says 48 hours for a full cure so I'll post back with results. Meanwhile, the Angels, Silver Dollar and Bristle Nose are enjoying a vacation in the 100 gal with Clowns and Yoyo Loaches, Barbs and Gourmies.  When the tank was full it had pushed the glass out about a half inch but when I drained it all the glass straightened back.

When you use the silicone, make an extra bead of it on some random piece of junk you're going to throw away and place it next to the tank. When you think it's cured, cut this extra blob in half and have a look - then you'll know for sure if it is completely cured, or if it's still liquid goo in the middle.
